1 Automated Storage Manager Overview
This documentation is intended for the person who administers HP StorageWorks X1000 Network
Storage Systems running Automated Storage Manager software.
ASM provides storage-allocation wizards that walk you through the process of allocating and
configuring storage on your HP Storage System to host application data and shared folders. The
storage-allocation wizards also allow you to schedule backups and snapshots of hosted application
data and shared folders.
Other wizards are provided to help you set up Exchange Server storage, SQL Server database
storage, user-defined application storage, and shared folders storage.
ASM is designed to work seamlessly with Windows administrator tools, HP Storage System
Management applications, Microsoft iSCSI Target, and Data Protector Express. For example, you
can change your HP Storage System's:
•
Storage allocations (quotas), shared folder permissions and names, and snapshot schedules
using ASM, Windows administrator tools, and the HP Storage System Management
applications.
•
Media rotation type using ASM and Data Protector Express.
IMPORTANT: Do not use Windows administrator tools to change the paths to storage configured
on your HP Storage System or file directories created by ASM on application servers with storage
hosted on your HP Storage System. Doing so will break the iSCSI communication paths between
your application servers and HP Storage System, and make it so ASM can no longer locate allocated
storage areas on your HP Storage System.
Software requirements
ASM comes preinstalled on your HP Storage System. A license key is not required for ASM.
Software support
Storage for application servers running on Windows Server 2003 with SP1 through Windows
Server 2008 R2 that are on the same domain as your HP Storage System can be hosted. Windows
domain controllers (such as Windows Small Business Server) are supported by ASM as managed
application servers.
ASM provides storage-management services for the following applications:
Table 1 Storage support on ASM
Microsoft Exchange Server 2003 with SP1 or later,
Exchange Server 2007, and Exchange Server 2010
See “Using the Host an Exchange Storage Group Wizard”
(page 10).
File sharing services on local storage
See “Using the Create a Shared Folder Wizard” (page 12).
Microsoft SQL Server 2000 with SP4 or later, SQL Server See “Using the Host a SQL Server Database Wizard”
2005 with SP2 or later, SQL Server 2008, and SQL Server (page 14).
2008 R2*
User-defined applications
See “ Using the Host a User-Defined Application Wizard”
(page 15).
* ASM does not support SQL Server 2008 databases that utilize FILESTREAM data type storage.
ASM does not support Internet Protocol version 6 (IPv6). When entering or configuring IP address
settings using ASM, use Internet Protocol version 4 (IPv4) addresses.
In order to use some Automated Storage Manager features, your HP Storage System must have
supporting software installed. Microsoft iSCSI Software target is preinstalled. HP Data Protector

Creating backups to tape, other disks, No
or other types of storage media
Using ASM with HP StorageWorks Storage Mirroring software
As of ASM version 4.0, HP StorageWorks Storage Mirroring (SWSM) software is no longer
integrated directly with ASM.
Support for LUNs over 2TB in size
ASM supports the provisioning of LUNs over 2TB in size on systems running Windows Storage
Server 2003 and Windows Storage Server 2008 and greater. ASM uses GUID Partition Table
(GPT) partitions to enable this new feature. All storage that is provisioned using ASM now uses
GPT partitions by default.
Limitations
•
Existing Master Boot Record (MBR) LUNs cannot be grown beyond 2TB. This includes local
volumes and iSCSI volumes.
•
iSCSI LUN volumes greater than 2TB are supported only if the iSCSI Target is running a
minimum of iSCSI Target version 3.2.
•
The maximum size allowed for a LUN is 256TB.
IMPORTANT: If you want to grow existing MBR partitions to a size exceeding 2TB, you must first
convert the MBR partition to a GPT partition. This can be accomplished by backing up the data
on the MBR partition and then deleting the MBR partition. A new GPT partition can then be created
and the data can be restored. For more information about GPT partitions, refer to Microsoft
Knowledge Base article KB302873.

The wizard does not migrate user-defined application data to
your HP Storage System or reconfigure the application to store
data on your HP Storage System. You must do this manually as
described in “Migrating user-defined application data from a
remote application” (page 25), and as described in the
application's documentation.

size and storage allocation.
Using the Host an Exchange Storage Group Wizard
The Host an Exchange Storage Group Wizard automatically discovers the Exchange storage groups
on your application server and helps you allocate and configure storage space for these components:
•
Mail stores—Contain the data in user mailboxes.
•
Public stores—Contain the data in public folders.
•
Logs—Provide a record of every message stored in a storage group.
Before you begin configuring storage for Exchange
10
•
Make sure the ASM agent is installed on each server with Exchange data you plan to host.
•
Make sure you have a current backup of your Exchange data and logs.
Hosting storage for applications and shared folders
Accessing the Host an Exchange Storage Group Wizard
1.
In the Actions pane, select Host an Exchange Storage Group.
The Host an Exchange Storage Group Wizard welcome page opens.
2.
Click Next to open the Specify Exchange Server page (see “Entering a name of a server that
hosts Exchange” (page 11)).
Migrating Microsoft Exchange 2010 mail stores
If you are attempting to migrate Microsoft Exchange 2010 mail stores that are replicated (that is,
configured in a DAG environment), it is not mandatory that the ASM agent be installed on the
other mailbox servers participating in the DAG to facilitate the replication. ASM can still migrate
the mailbox and the log files for the replicated database by stopping replication between the
participating servers, and then restarting replication after the migration is complete.
If your replicated mail stores share their mail box database path or the log file path with another
mail store (replicated or not) they will not be shown as candidates for migration.
For a replicated Exchange 2010 mailbox, if the mailbox database path and the log files path for
an Exchange 2010 mailbox are on the same folder before migration, discovery is required after
migration for a proper reconciliation. After migration and before the subsequent discovery, you
will see only one app area for the migrated Exchange 2010 mailbox. After the discovery, ASM
will properly reconcile the app areas to show two different app areas under the storage group
instance.
Entering a name of a server that hosts Exchange
Use the Specify Exchange Server page to provide ASM with the name or the Internet Protocol
address (IPv4) of a remote server in your current domain that hosts Exchange.
1.
2.
Do one of the following:
•
Enter the host name of a server that hosts Exchange (exactly as it is registered in the
domain).
•
Enter the IP address (IPv4) of a server that hosts Exchange.
Click Next to open the Select Storage Group Components page (see “Selecting Exchange
storage group components” (page 11)).
Selecting Exchange storage group components
Use the Select Storage Group Components page to select the Exchange storage group and storage
group components (mail stores, public stores, and logs) you want to host on your HP Storage
System and manage using ASM.
Using the Host an Exchange Storage Group Wizard

in the Select Storage Group Components page in the wizard if this feature is enabled. They are
selected in the same manner as other Exchange components.
NOTE: It is not recommended to host both the LCR and the original Exchange components on a
single HP Storage System.
Using the Create a Shared Folder Wizard
The Create a Shared Folder Wizard walks you through the process of creating a top-level shared
folder (file share) on your HP Storage System, including allocating and configuring the required
storage.
NOTE: You cannot create nested shared folders on your HP Storage System using ASM. You
may use other applications, such as Windows Explorer or the Shared Folder MMC snap-in, to
create nested shared folders on your HP Storage System.

server. Upon completion, you can monitor and manage storage for the application through the
Automated Storage Manager.
After storage is allocated and configured on your HP Storage System for a remote application
using the Host a User-Defined Application Wizard, do the following:
•
Manually migrate the remote application's data to your HP Storage System. See “Migrating
user-defined application data from a remote application” (page 25) for more information.
•
Configure the remote application to store its data on the iSCSI LUN exported by ASM to the
application server as described in the application's documentation.
Before you begin configuring storage for a user-defined application
•
Make sure the ASM agent is installed on each application server with data you plan to host.
•
Make sure you have a current backup of your remote application data and logs.
•
For an iSCSI LUN application, you will need the iSCSI Qualified Name (IQN).
NOTE: For a remote Windows application, you need to know the path to the iSCSI LUN on the
application server to configure the remote application to store data on the iSCSI LUN. The path to
the iSCSI LUN is displayed on the application's Properties window on the Storage tab.
To access the Host a User-Defined Application Wizard
1.
In the Actions pane, select Host a User-Defined Application.
The Host a User-Defined Application Wizard welcome page opens.
2.
Click Next to open the Choose type of Application page (see “Choose type of application”
(page 16)).
Choose type of application
1.
Select the type of application for hosting a user-defined application:
•
Remote Windows Application: ASM will provision storage for the application and expose
the storage to the given server as an NTFS volume over the iSCSI protocol. This is the
recommended option for most scenarios. The Automated Storage Manager agent must
be installed on the application server to use this option.
•
iSCSI LUN: Exposes a LUN to the remote server so the server can store data on the LUN.
You will need to install an iSCSI initiator on your host server. Storage is provisioned for
these applications.
NOTE: A valid iSCSI Qualified Name (IQN) is required to host a user-defined application
as an iSCSI LUN. IP addresses are not valid IQNs. If you enter a temporary IQN (such
as an IP address) in the iSCSI Qualified Name (IQN) field, you must manually configure
the iSCSI Target using the Microsoft iSCSI Software Target management console in order
for ASM to discover and assign the application server to the iSCSI LUN.
•
2.
Local storage only: Creates a volume on your HP Storage System. Storage is provisioned
for these applications.
Click Next to open the Enter an Application Name page (see “ Entering an application name”
(page 17)).
When hosting a user-defined application as an iSCSI LUN, the volume presented is not automatically
initialized with NTFS and mounted. This is because the iSCSI LUN could be presented to a
non-Windows server. After completing the wizard, you must manually initialize and mount the
volume.

for your virtual library.
When you are done, click Next to open the Storage Allocation page (see “Allocating space
for components” (page 17)).
NOTE: The number of slots needed for your virtual library will depend on the media rotation
type chosen for the backups that will use the virtual library. The number of slots must be high
enough to support the rotation type you intend to use for scheduling backups to this virtual
library. See Planning for Media Rotation in the Data Protector Express User's Guide and
Technical Reference for more information.

Physical disk type
Type of physical disk to add for the hot spare.
You are able to choose SAS, (Serial

physical disk type, depending on your
hardware.*
RAID level
Hard drive formatting that provides different levels
of performance, capacity, and data protection.
For more information about RAID levels,
see “Customizing RAID levels”
(page 20).*
Hot spare required
A hot spare is a hard drive reserved as a spare for
storage space configured as RAID 1, 1+0, 5, or 6.
A hot spare automatically replaces a hard drive
when it fails. When the failed hard drive is replaced,
its replacement becomes the new hot spare.
A hot spare is assigned at the array

*After you have allocated and configured storage for an application component, user-defined application, or shared
folder using a wizard, you can change the allocated space size, change the percent full warning threshold, and change
the enforced allocated limit (shared folders and local storage applications). However, you cannot change the RAID
level, RAID stripe size, Hot Spares, or Physical Disk Type.
Customizing RAID levels
Before you customize the default RAID level setting, review Table 6 (page 21) to see how the
different RAID levels affect performance, capacity, and data protection level.
Unless you customize the advanced configuration settings, the wizard configures the storage space
with the default values shown on the Advanced window:
•
For Exchange and SQL Server, the wizard suggests default settings based on HP storage best
practices and specific recommendations for Exchange storage group and SQL Server database
components. You should generally accept these defaults.
•
For user-defined applications and shared folders (where industry-standard recommendations
cannot be determined), the wizard provides default settings you can customize.
Table 6 (page 21) shows how the different RAID levels affect:
20
•
Performance–The speed at which data is read from and written to the hard drives. The RAID
level with the best performance rating provides the fastest reads and writes.
•
Capacity–The available storage space on the hard drives. The RAID levels with the best
capacity rating require the least amount of storage space to store data.
•
Data protection–The number of hard drives that can fail without data being lost. The RAID
level with the best data protection rating allows more hard drives to fail before data is lost.
Hosting storage for applications and shared folders
Table 6 Descriptions of RAID levels
RAID level
Description
No RAID
Offers no protection against disk failure. If a disk drive fails, data is lost.
RAID 0 – Striping (No Fault Tolerance)
Offers the greatest capacity and performance without data protection. If
you select this option, you will experience data loss if a hard drive that
holds the data fails. However, because no logical drive capacity is used
for redundant data, this method offers the best capacity. This method offers
the best processing speed by reading two stripes on different hard drives
at the same time and by not having a parity drive.
RAID 1 – Mirroring
Offers a good combination of data protection and performance. RAID 1
or drive mirroring creates fault tolerance by storing duplicate sets of data
on a minimum of two hard drives. There must be an even number of drives
for RAID 1. RAID 1 and RAID 1+0(10) are the most costly fault tolerance
methods because they require 50 percent of the drive capacity to store the
redundant data. RAID 1 mirrors the contents of one hard drive in the array
onto another. If either hard drive fails, the other hard drive provides a
backup copy of the files and normal system operations are not interrupted.
RAID 1+0 – Mirroring and Striping
Offers the best combination of data protection and performance. RAID 1+0
or drive mirroring creates fault tolerance by storing duplicate sets of data
on a minimum of four hard drives. There must be an even number of drives
for RAID 1+0. RAID 1+0(10) and RAID 1 are the most costly fault tolerance
methods because they require 50 percent of the drive capacity to store the
redundant data. RAID 1+0(10) first mirrors each drive in the array to
another, and then stripes the data across the mirrored pair. If a physical
drive fails, the mirror drive provides a backup copy of the files and normal
system operations are not interrupted. RAID 1+0(10) can withstand multiple
simultaneous drive failures, as long as the failed drives are not mirrored to
each other.
RAID 5 – Distributed Data Guarding
Offers the best combination of data protection and usable capacity while
also improving performance over RAID 6. RAID 5 stores parity data across
all the physical drives in the array and allows more simultaneous read
operations and higher performance than data guarding. If a drive fails, the
controller uses the parity data and the data on the remaining drives to
reconstruct data from the failed drive. The system continues operating with
a slightly reduced performance until you replace the failed drive. RAID 5
can only withstand the loss of one drive without total array failure. It requires
an array with a minimum of three physical drives. Usable capacity is N-1
where N is the number of physical drives in the logical array.
RAID 6– Advanced Data Guarding (ADG) Offers the best data protection and is an extension of RAID 5. RAID 6 uses
multiple parity sets to store data and can therefore tolerate up to 2 drive
failures simultaneously. RAID 6 requires a minimum of 4 drives and is
available only if the controller has an enabler. Writer performance is lower
than RAID 5 due to parity data updating on multiple drives. It uses two disk
for parity; its fault tolerance allows two disks to fail simultaneously. Usable
capacity is N-2 where N is the number of physical drives in the logical
array.
Setting a percent full warning threshold
To receive a warning alert when storage capacity reaches a specified limit, set the percent full
warning threshold. You can set a warning threshold for any application component, user-defined
application, and shared folder that ASM manages. An iSCSI LUN application will not have a
warning threshold.
By default, the warning threshold is set to 80%. To change it, enter a new percent value on the
Advanced window.
After you set a warning threshold, ASM changes the status indicator for the application component,
user-defined application, or shared folder when this threshold has been surpassed. This is a warning
Allocating space for components

only; no hard limits are enforced on storage capacity as a result of setting this value. The warning
is visible in these places:
•
A yellow warning icon appears on the application component, user-defined application, or
shared folder icon in the content pane.
•
As an alert in the Properties window.
NOTE: For shared folders and local storage applications, you can set an enforceable limit (or
quota) for allocated storage, as well as a warning threshold. For more information, see “Enforcing
an allocated storage limit for shared folders and local storage applications” (page 22).
Enforcing an allocated storage limit for shared folders and local storage applications
ASM provides a way to enforce an allocated storage limit for shared folders and local storage
applications. If enforced, the system does not allow the amount of allocated space for a shared
folder and local storage application to be exceeded.
If the capacity of the shared folder and/or local storage application surpasses the percent full
warning threshold and reaches the allocated space limit, the status changes from Warning to
Critical in the content pane, and users are blocked from adding data to the shared folder and
local storage application.
ASM does not support enforcing an allocated storage limit (or quota) for parent folders of shared
folders that are created and managed using ASM.
NOTE: If you do not choose to enforce an allocated storage limit for a shared folder, the ASM
status indicator still goes from Warning to Critical in the content pane; however, users are not
blocked from adding data to the shared folder as long as there is still unallocated storage space
on the logical disk where the shared folder resides. Data can be written to the shared folder until
the logical disk is full.
By default, the Enforce Allocated Limit (Quota) is set to No for all shared folders and local storage
applications. To change this setting, do one of the following:
•
Using the Create a Shared Folder Wizard, change the Enforce Allocated Limit (Quota) setting
on the Advanced window to Yes.
•
Select the shared folder in the content pane, click Properties in the Actions pane, click the
Warning Threshold tab, and then select the Enforce Allocated Limit (Quota).
NOTE: If a Shared Folder is created outside of ASM, you must use the Warning Threshold property
tab on the particular folder to enable the Enforce Allocated Limit (Quota) setting.
To allocate space for a shared folder, specify a size using the Allocate Space Wizard as described
in “Increasing or reducing the allocated storage” (page 33).
Selecting data protection
Use the Data Protection window in the wizard to select the following:
•
Snapshots (Local disk backup) Previous versions of data are retained on disk using virtual
library backups and/or volume snapshots for fast recovery. See “Scheduling snapshots”
(page 23) for more information.
•
Tape or Other Device (Alternate location backup) Data is copied off of this HP Storage System
to tape, other disks, or other types of storage media. This enables long term storage and
disaster recovery. See “Scheduling backups” (page 23) for more information.
From this window, you can also click Modify advanced properties to configure advanced settings
for backups.

You can view a read-only copy of a snapshot of an Exchange storage group, SQL Server database,
or user-defined application by exposing the snapshot on your HP Storage System. Exposing a
snapshot allows you to view the contents of a snapshot and selectively revert files.
NOTE: A snapshot of a shared folder cannot be exposed or unexposed using ASM. Use the
Shadow Copy Client to view snapshots of shared folders from a client computer. Snapshots of a
shared folder are stored on the same logical disk as the shared folder, in a protected system folder.
To expose a snapshot:
1. Select an Exchange storage group, SQL Server database, or user-defined application in the
content pane.
2. In the Actions pane, click Snapshots and then click Manage Snapshots. The Manage Snapshots
dialog box displays.
3. Select either Latest data or a snapshot from the list and then click Expose. The Expose Snapshot
dialog box displays.
Latest data represents the most current data on the system. The snapshot that is taken represents
reflects the data that is on the system at that specific point in time.
4.
5.
Do one of the following:
•
Select Mount as a volume on a remote Windows system running the All-in-in-One Storage
Manager Agent to expose the snapshot on a mount point on a remote server. Type the
IP address (IPv4) or hostname and mount path of the remote server in the provided fields.
•
Select Expose as a Windows share (SMB protocol) to expose the snapshot on a local
Windows share.
•
Select Expose as an iSCSI LUN to an iSCSI Initiator to expose the snapshot to a remote
iSCSI initiator. Type the iSCSI Qualified Name of the iSCSI Initiator in the provided field.
Click Expose.
Unexposing a snapshot
After restoring from a snapshot, you may choose to unexpose a snapshot; unexposing a snapshot
completely removes access to it. Note that unexposing a Latest data will result in that snapshot
also being removed.
NOTE: A snapshot of a shared folder cannot be exposed or unexposed using ASM. Use the
Shadow Copy Client to view snapshots of shared folders from a client computer. Snapshots of a
shared folder are stored on the same logical disk as the shared folder, in a protected system folder.
To unexpose a snapshot:
1. Select an Exchange storage group, SQL Server database, or user-defined application in the
content pane.
2. In the Actions pane, click Snapshots and then click Manage Snapshots. The Manage Snapshots
dialog box displays.

Reverting data to snapshots
ASM allows you to revert data stored on your HP Storage System to a snapshot. This overwrites
the existing data and reverts it to a past state.
NOTE:
•
Snapshots of shared folders cannot be reverted using ASM. To revert a shared folder to a
past snapshot, use the Shadow Copy Client.
•
Snapshots of user-defined applications that are configured as local storage only applications
cannot be reverted using ASM because all data that is on the same volume as the application
would also be reverted.

Installing Data Protector Express on other machines
The Data Protector Express installation on the HP Storage System acts as the master server for a
Data Protector Express Management Domain. If you wish to use the ASM system as a Disk-To-Disk
(D2D) backup target for other clients or servers, you may install Data Protector Express on those
machines and join the management domain.
NOTE:
Installing Data Protector Express on other servers is not required to backup Exchange,
SQL Server, or User-Defined applications, when those applications are hosted by ASM. The
instructions provided here are only needed if a user wishes to use ASM as a backup target for
additional user data in their environment.
You can download Data Protector Express from http://www.hp.com/go/dataprotectorexpress.
1.
2.
When installing Data Protector Express on another machine, select Join an existing Data
Protector Express domain.
When prompted, provide the hostname or IP address (IPv4) of the HP Storage System.
An unlimited number of client platforms such as Windows XP, Vista, and Windows 7 may be
added to the Data Protector Express domain managed by the HP Storage System. Server platforms
such as Windows Server 2003 or 2008 will require one license per protected server.
For Data Protector Express 4.0, the following license is required to add a server to the backup
domain:HP Data Protector Express Network Client Agent BB121AA. For Data
Protector Express 5.0, the same license is used to create the initial backup domain on the first
server and to add additional servers to the domain. This license is sold in packs of 1, 3, or 10
servers; (TC330A, TC331A, or TC332A).
You may use ASM to create and manage storage for Data Protector Express virtual libraries on
the HP Storage System. You may then create backup jobs in Data Protector Express that use these
virtual libraries as targets for Disk-to-Disk backups of your protected clients and servers. See “Using
the Create a Virtual Library Wizard” (page 17) for more information.
NOTE: When manually creating or modifying backup jobs that were not created by ASM, do
not use the Data Protector Express ASMbackup account. It is recommended that you create other
Data Protector Express user accounts as needed.

Managing data protection
5 Managing storage
After an application is hosted or shared folder is created on your HP Storage System using a
storage-allocation wizard, you can manage its storage and data by:
•
“Increasing or reducing the allocated storage” (page 33)
•
“Changing the percent full warning threshold” (page 33)
•
“Removing application areas from view” (page 34)
•
“Changing permissions, names, descriptions, or paths of shared folders” (page 34)
•
“Deleting shared folders” (page 35)
Increasing or reducing the allocated storage
You can increase or reduce the storage allocated to an application component, user-defined
application, or shared folder after storage is initially allocated and configured using a
storage-allocation wizard.
Increasing the storage allocated requires ASM to grow the logical disk (increase the amount of
hard drive space allocated to the logical disk) holding the data. Reducing the allocated storage
does not reduce the size of the logical disk holding the data, because once hard drive space is
allocated to a logical disk, it cannot be unallocated due to the configuration of hard drives.
NOTE: Unallocated storage on a logical disk is re-allocated by ASM when new or additional
storage is allocated to an application component or shared folder and the advanced configuration
values selected for the storage matches those of the logical disk.
For example, if an application component or shared folder's allocated storage is increased, any
unallocated space on the logical disk where it resides is used before the logical disk grows.
1.
2.
3.
Select the application component, user-defined application, or shared folder in the content
pane.
In the Actions pane, click Allocate Space to open the Allocate Space wizard.
Change the size value:
•
Highlight the storage size unit value and then enter a new value as necessary: megabytes
(MB), gigabytes (GB), or terabytes (TB).
•
Highlight the storage size number value and enter a new value, or click the arrow buttons
to change the value.
The Size Range field shows the minimum and maximum storage space that can be allocated
to an application component, user-defined application, or shared folder. Whenever you
change the storage space allocated to an application component or change an advanced
configuration setting for an application component, the maximum value for Size Range is
recalculated for each application component shown.
4.
Click Next to open the Review Tasks Summary page (see “Reviewing task summary and
scheduling tasks” (page 24)) for more information.
Changing the percent full warning threshold
You can change the percent full warning threshold value for an application component, user-defined
application, or shared folder after storage is initially allocated and configured using a
storage-allocation wizard. See “Setting a percent full warning threshold” (page 21) for more
information.
Increasing or reducing the allocated storage
33
NOTE: For shared folders, you can set an enforced limit (quota) for allocated storage, as well
as a warning threshold. For more information, see “Enforcing an allocated storage limit for shared
folders and local storage applications” (page 22).

Click OK.
Removing application areas from view
You can remove application components and user-defined applications from view on the ASM
user interface. This allows you to remove storage information from the content pane pertaining to
storage allocations lost due to hard drive failure or storage for an application component or
user-defined application whose storage you plan to unhost.
Removing an application component or user-defined application from view does not unhost its
storage. Its storage is still hosted on your HP Storage System. To permanently remove storage from
your HP Storage System, you must first remove the storage that is hosted by ASM.
NOTE: If you remove an application component or user-defined application from view without
unhosting the storage, your HP Storage System will re-discover the applications immediately.
NOTE: This action is not available for shared folders. Because ASM automatically discovers
top-level shared folders on your HP Storage System, the folder would just reappear after the next
discovery process. A shared folder is automatically removed from view when it is removed from
your HP Storage System.
To remove an application component or user-defined application from view:
1.
2.
3.
Permanently remove storage from your ASM, depending on the type of application. The
application component will still remain in the content pane.
Select the application component or user-defined application to remove in the content pane.
In the Actions pane, click Remove from View.
A confirmation dialog box opens.
4.
Do one of the following:
•
Click OK to remove the item from view.
•
Click Cancel to cancel the action.
Changing permissions, names, descriptions, or paths of shared folders
ASM cannot be used to change permissions, names, descriptions, or paths of top-level or nested
shared folders that reside on your HP Storage System. Use Windows Explorer or the Shared Folder
MMC snap-in to change permissions, names, descriptions, or paths of shared folders that reside
on your HP Storage System.
ASM automatically discovers and adopts any changes you make to the permissions, names,
descriptions, or paths of shared folders using other applications. You do not have to make any
changes in ASM to implement the changes. Click Refresh in the Actions pane (or perform any
action in ASM) to update the ASM user interface to display your changes.

Monitoring storage
The total capacity of your HP Storage System is divided into the following areas:
•
Exchange—Storage allocated to host Exchange storage group components.
•
Shared Folders—Storage allocated to host shared folders.
•
SQL Server—Storage allocated to host SQL Server database components.
•
User-defined—Storage allocated to host user-defined applications.
•
Data Protection — Storage allocated to host snapshots, backups, and replicated data.
•
Unallocated—Unused storage that is not allocated.
The unallocated space value is the total unused space on your HP Storage System that has
not been allocated to host application or shared folder storage. Unallocated storage includes
raw (unconfigured) storage and unused configured storage (logical disks).
•
Unmanaged—Storage used by data that is not managed by ASM.
The unmanaged value is the total storage being used to store data not managed by ASM,
such as application or shared folder data no longer managed by ASM because the application
components or shared folder was removed from view (see “Removing application areas from
view” (page 34)) and any other data saved on your HP Storage System that is not managed
by ASM.
NOTE: Logical disks (LUNs) being used to store application data or shared folders cannot be
grown (increased in size) by ASM using space on unused logical disks (configured storage); they
can only be grown using raw storage.
Unused logical disks are reallocated by ASM when an unhosted application component, shared
folder, or user-defined application's storage is hosted using a storage-allocation wizard and the
advanced configuration settings selected in the wizard match those of the unused logical disk. You
can find the advanced configuration settings and capacities of unused (and used) logical disks on
the Properties window for each logical disk (see “Accessing properties for HP Storage System
logical disks” (page 47)).
Automated Storage Manager Alerts
ASM generates an alert when the status of an application area or storage area changes from OK
to Warning or Critical. The alerts describe the condition that caused the storage status to change.
When an alert is generated, a One or more alerts exist message appears in the ASM content
pane. Click the message to display a list of current ASM alerts.
NOTE: ASM rolls up any status alert to the highest level. For instance, if a shared folder has
surpassed its percent full warning threshold and exceeded its allocated storage space, a warning
icon is shown on the shared folders pool icon. Likewise, if a critical status exists in an Exchange
mail store, the critical icon is also shown on the Exchange storage group icon.

7 Troubleshooting Automated Storage Manager
The following list documents recommended workarounds for conditions related to Automated
Storage Manager. For information specific to a particular product release, see the HP Automated
Storage Manager Release Notes for your product version.
The ASM Grow/Extend Volume command fails intermittently.
The Grow/Extend Volume command sometimes returns a failure even though the operation completes successfully and
the volume capacity matches the requested size.
Workaround: Retry the operation after completing the Discovery process.
Backup and/or Restore operations in ASM may fail if there is more than one File Volume (partition) configured on an
iSCSI-Based LUN (disk)
Workaround: Do not perform backup or restore operations in ASM on storage where more than one File Volume is
hosted on a single iSCSI LUN. ASM never provisions more than one volume on iSCSI LUNs, and this situation will not
be encountered for storage provisioned by ASM.
Data protection settings are not modified for storage areas that are promoted by ASM
If data protection settings (snapshots and backup) are applied to a remote user-defined storage area, and then a SQL
Server database or Exchange database is manually migrated to this storage area, ASM automatically promotes the
application to a SQL or Exchange Storage area during the discovery process. ASM does not, however, adjust the
data protection settings that were originally applied to the area. This may lead to failures when taking snapshots or
running backups.
Workaround: When SQL Server or Exchange databases that are part of user-defined storage areas are promoted to
SQL or Exchange storage areas in ASM, disable and delete all data protection settings for those areas (snapshots and
backup) and reset them using ASM.
Troubleshooting Data Protector Express
This section describes workarounds for conditions related to HP StorageWorks Data Protector
Express (DPX), a service required to enable data protection features on the HP ASM. Note that
DPX is not installed on HP StorageWorks X1000 Network Storage Systems by default. The following
applies only to storage systems with DPX installed and enabled.
DPX Virtual Tape Libraries show up as User Defined Applications in ASM after running System Recovery
DPX Virtual Tape Libraries that are not backed up prior to running the System Recovery process appear as User-Defined
Applications in the ASM UI after the system recovery process is complete.
Workaround: Before running System recovery, back up all DPX files and configuration settings and reapply them after
the System Recovery process is complete.
Changes made to a backup using Data Protector Express are not always reflected in ASM
If you use Data Protector Express to change the rotation type associated with a backup to Custom rotation, the change
is not reflected in ASM.
Workaround: Data Protector Express can be used to change the rotation type of a backup to Custom rotation, however,
this change will not be reflected in ASM. If you need to use a custom rotation, HP recommends that you continue to
use Data Protector Express to make any further changes to the backup.
52
Troubleshooting Automated Storage Manager
Backup job fails for Exchange storage groups that were manually migrated to the storage system
It is possible to manually create a virtual hard disk on the storage system using the Microsoft Software iSCSI Target
snap-in. This disk may then be assigned to a target, allowing an iSCSI initiator on the Exchange server to access the
disk as a local volume.
If the logs and database(s) of an Exchange storage group are then moved to this iSCSI volume, ASM will discover the
Exchange Storage Group, and present it as an application in the ASM user interface. This will allow you to configure
data protection for the application and schedule a DPX backup; however, when the backup job runs, it fails.
The job status in DPX will be operator canceled, and the following error is written to the Windows application event
log on the storage system:
Stopping backup job '<job name>' due to checksum verification failure.
The error occurs because ASM performs checksum verifications using the eseutil.exe utility on Exchange databases
and logs before backing up the files. Databases and logs are expected to be found in separate volumes as a best
practice method employed by ASM when a wizard is used to migrate an Exchange storage group to the storage
system. When the logs are not found, the checksum fails and ASM cancels the backup job and notifies Exchange that
the backup did not complete successfully.
Workaround: Manually create another iSCSI virtual hard disk and make it accessible to the Exchange server:
1. Use the Exchange Management Console to move the storage group path for the log files and system files to the
new volume, leaving the database at the original iSCSI volume.
2. After modifying the paths in Exchange, click Refresh in the ASM user interface to force a discovery.
3. The application area for log files will now show an alert. Right click on this area and select Remove from view.
4. Another discovery will be performed and ASM will restore the log file area into the user interface with corrected
properties, such as the new location on the Exchange server.
For backup jobs from ASM to work properly, each database and the log files/system files must be on a separate iSCSI
volume. For example, if a storage group contains one mail store and one public folder store, three iSCSI volumes
should be used, one for each database, and one for the log and system files.
Performing a “Remove from View” on a Virtual Library causes the library to appear as a User-Defined application
If a virtual library is deleted from Data Protector Express, and then the Remove from View option is used on the virtual
library in ASM, the virtual library is removed from the Data Protection view, but appears in the User Defined view.
Workaround:
1. Use Data Protector Express to stop and then delete the Virtual Library Device.
a. In Data Protector Express, select the Devices icon from the Favorites pane on the left.
b. In the right pane, navigate until the desired device is displayed.
c. Right-click the Virtual Library device and select Stop.
d. After the device has been stopped, right-click again and select Delete.
2. Delete the storage folder used by Data Protector Express to store the backup data. The storage folder path can be
found by right-clicking on the virtual library in ASM, selecting Properties, and then selecting the Storage tab.
3. Right-click on the virtual library in ASM and select Remove from view.
