than 2GB RAM it will not proceed with the installation or upgrade.
7. For machines installed with 64bit CPU, AhsayUBS will now only run in 64 bit
mode. The option to switch to 32bit mode has been removed from the
AhsayUBS "System Management Console (64bit)" menu.
8. For machines installed with 32bit CPU. The option to switch to 64bit mode
has been removed from the AhsayUBS "System Management Console
(32bit)" menu.
9. Existing AhsayUBS installations on 64bit machines, which were running in
32bit mode prior to upgrade. Will automatically boot up in 64bit mode after
upgrading to AhsayUBS v2.5.2.0 or above.
10.AhsayUBS is not supported running as a guest O/S under Microsoft Hyper-V
as FreeBSD 8.2-stable release is not a supported Hyper-V guest O/S.
11.Supports the upgrade of AhsayUBS installations from v1.1.0.0 onwards.
12.The upgrade of AhsayUBS installations running on both the UFS storage
model and the previous ZFS storage model.

1.2 The UFS storage model
For backwards compatibility with older AhsayUBS versions, the UFS storage
model is also supported. After upgrading, the 'geom_concat.ko',
'geom_stripe.ko', and 'geom_raid5.ko' module will be loaded by the FreeBSD
to support the UFS storage model. To check if these kernel modules have been
loaded correctly you can run the “kldstat” command, which will return the
following output.
The 'Master Storage Device' on AhsayUBS v2.3.0.0 is preserved in UFS format
which is mounted on '/ubs/mnt/eslsfw' upon system boot time. The following
example shows a UFS filesystem mount as '/ubs/mnt/eslsfw'.
The Optional Labelled Device in the old AhsayUBS will migrated in this version
of AhsayUBS which is one of the storage types called “Optional Storage” inside
the “Additional Storage”. Volume status and UFS filesystem integrity checking
(fsck) are also available in this AhsayUBS version. For details, please refer to
the section [Storage].

1.3 The ZFS storage model
AhsayUBS v2.5.2.0 is implemented with ZFS v5 and ZPOOL v28. The existing
ZPOOL(s) will not be upgraded and only newly created ZPOOL will be applied
with the ZIL. As the ZFS storage model is based on a GMIRROR and ZFS
design, therefore the 'geom_mirror.ko', 'opensolaris.ko', and 'zfs.ko' kernel
modules will be loaded by the FreeBSD. The GEOM kernel modules used
previously for UFS support 'geom_concat.ko', 'geom_stripe.ko', and
'geom_raid5.ko' will also be loaded. To check if these kernel modules have
been loaded correctly you can run the “kldstat” command, which will return
the following output.
The 'Master Storage Device' on AhsayUBS is configured as a ZPOOL with the
following pool name 'eslsfwx{UID}' format. The ZFS pool will be mounted on
'/ubs/mnt/eslsfw' upon system boot time. The following example shows a
zpool volume of size 191GB “eslsfwx839830C2” mount as '/ubs/mnt/eslsfw'

GPT Boot - {UID}xesgpbt
Operating System Framework - {UID}xesosfw
Firmware Module Framework - {UID}xesfmfw
Note:
For production AhsayUBS servers configured with ZFS volume(s). It is strongly
recommended to install at least 4 GB RAM, as ZFS volumes require relatively
large amount of memory to run. The amount of memory required is dependent
on the size of the ZFS volume and the amount of I/O activity.

1.4 ZFS Integrity Checking
In order to safeguard the data integrity of the files on the ZFS volume, a weekly
“zpool scrub” (zpool volume data integrity check) is performed starting at 00:00
every Sunday morning. To verify the checksums of all the data in the specified
ZFS pools are correct. The scheduled started time of the “zpool scrub” is
currently not user configurable and it cannot be disabled in this version of
AhsayUBS. Once the “zpool scrub” job has started it is not possible to stop it.
To check the status of the “zpool scrub”, you can use the “zpool status”
command which will return the following output. For the following example the
“zpool scrub” has checked 56.33% of the pool: eslsfwx839830C2
If an additional data integrity check is required in between the scheduled weekly
checks. It is possible to initiate a manual “zpool scrub” using the “zpool scrub {%
POOL_NAME%}” command. As with the weekly “zpool scrub”, the AhsayOBSR
service and backup/restore operations can continue to run as normal.
Note:
There may be some performance overhead associated with a “zpool
scrub”, i.e. CPU utilization, memory, and increased I/O activity. The
performance overhead is proportional to the amount of data on the ZFS
volume.

1.5 FreeBSD and ZFS Implementation
The ZFS version 5 and ZPOOL v28 on AhsayUBS has undergone an extended
period of intensive performance and load testing, which has consistently
delivered superior performance and data integrity results in comparison to UFS.
1.6 Storage Model Migration
For existing AhsayUBS customers who wish to migrate from UFS to ZFS storage
model, only a manual migration method is available.
The migration process will involve:
i.
ii.
iii.
Copying the existing user data from AhsayUBS server to another storage
device.
Use the latest AhsayUBS installer to install a new version of AhsayUBS on
the existing machine, which will overwrite all existing data.
Copy the user data from the storage device back to the AhsayUBS server.

The process to setup Ahsay Universal Backup System (AhsayUBS)
firmware on a machine is divided into 4 stages:
1. Installer Image Deployment
Deploys Ahsay Universal Backup System Installer image on removable
storage devices / CD-ROM / DVD-ROM
2. Firmware Installation/Upgrade
Install / upgrade Ahsay Universal Backup System Firmware into a
machine.
3. Ahsay Universal Backup System Configuration
Configures the Ahsay Universal Backup System Firmware.
4. Backup Server Configuration
Configures the Backup Server and Replication Server (AhsayOBS and
AhsayRPS)
There are different software/hardware requirements for each stage.
Please ensure that all the requirements are met before deploying the
Ahsay™ Universal Backup System to the machine. For information on
the software/hardware requirements, please refer to Chapter 4 System
Requirements of this document.
2.1 Ahsay Universal Backup System Firmware
AhsayUBS Firmware is a customized FreeNAS firmware with AhsayOBS &
AhsayRPS bundled and it is optimized to run AhsayOBS & AhsayRPS. Apart
from AhsayOBS & AhsayRPS, it also contains some basic features that system
administrator require, e.g. SSH and system monitor.
2.1.1 AhsayUBS Storage Concepts
The AhsayUBS installer will automatically detect all available local hard disk(s)
during the installation progress. The selected hard disk(s) will be partitioned to
form “Systsem Storage”. Several RAID devices will be created on the “System
Storage”:
i. GPT Boot (GPBT)
ii. Operating System Framework (OSFW)
iii. Firmware Module Framework (FMFW)
iv. Logical Storage Framework (LSFW)
The GPBT, OSFW and FMFW volume are configured as RAID1 in UFS file
system to form the core system. The LSFW RAID device:
- Supports JBOD, RAID0, RAID1 and RAID5 in UFS format for old version of
AhsayUBS.
Ahsay Systems Corporation Limited

(October 17, 2013)
Ahsay Universal Backup System
Administrator’s Guide
We back up your business
- Supports RAID0, RAID1 and RAIDZ in ZFS format for the new version of
AhsayUBS (The raid type depends on the number of hard disks installed and
selected during AhsayUBS installation, for RAID0 the minimum number of
disks is required is 1, for RAID1 and RAIDZ the minimum number of disks
required is 2).
These volumes are named “System Storage”. The OSFW, FMFW devices will be
created on the Unix File System (UFS). The firmware configuration files will be
stored on OSFW and the AhsayOBS & AhsayRPS configuration files and backup
data will be stored on LSFW.
If the LSFW file system runs out of disk space, extra storage can be added to
the system by either:
i. Adding a new block device to the system hardware.
ii. Creating an iSCSI connection to a remote storage server.
The added block devices will be partitioned and formatted to form "Modular
Storage (ZFS + ZIL)". The previously suported additional storage 'Modular
Storage (ZFS)', 'Expandable Storage (ZFS)' and 'Optional Storage (UFS)' will
also be listed in the summary page. However, only removal of those additional
storage is allowed. Expandable Storage volumes (ZFS) can no longer be
created.
There are three types of Additional Storage:
i. Modular Storage (ZFS / ZFS+ZIL)
- can be created by one or more local block device to form a volume
either in RAID0, RAID1 or RAIDZ (is dependent on the number of hard
disks used to form the volume). Since this AhsayUBS version, the
underlying ZPOOL will be added with a ZIL layer.
ii. Expandable Storage (ZFS)
- created in the former AhsayUBS versions with a hardware raid volume
or an iSCSI initiator session connected to this AhsayUBS machine. A
RAID0 ZFS filesystem will be formed for each of the Expandable Storage.
It is for supporting the old migrated AhsayUBS only and cannot be
created in this version of AhsayUBS.
iii. Optional Storage (UFS)
- called “Optional Labelled Device” on earlier AhsayUBS versions. It is
for supporting the older migrated AhsayUBS installations only and
cannot be created in this version of AhsayUBS.
By configuring the AhsayOBS & AhsayRPS, the “Additional Storage” can be
used as additional storage for storing server configuration files and backup
data.

4. System Requirements
This chapter describes the system requirements for the Installer Image
Deployment, Backup System firmware Installation/ Upgrade, Backup
System and Backup Server Configuration.
4.1 Backup System Requirements
The selected machine must meet the following requirements:




CPU: At least 1 CPU that is FreeBSD i386 / amd64 compatible.
Memory Size: 2 GB minimum
Disk Storage Space: 100GB per disk minimum
Network interface card (NIC): At least 1 NIC that is FreeBSD i386/amd64
compatible.
If an AhsayUBS server motherboard supports Unified Extensible Firmware
Interface (UEFI) standard. The boot mode must set to BIOS boot manager and
the AhsayUBS installed hard disk specified as the first the boot device.
If the AhsayUBS installer detects that the machine is installed with
less then 2GB RAM the installation or upgrade process will be aborted.
AhsayUBS is not supported running as a guest O/S under Microsoft
Hyper-V, as FreeBSD 8.2-stable release is not a supported Hyper-V
guest O/S.
For production AhsayUBS servers configured with ZFS volume(s). It is strongly
recommended to:
i. Install AhsayUBS on a 64bit machine.
ii. Install at least 4 GB RAM, as ZFS volumes require relatively large
amount of memory to run. The amount of memory required is
dependent on the size of the ZFS volume and the amount of I/O activity.
For the list of FreeBSD i386/amd64 compatible processors, please refer to
Appendix A.
WARNING:
For 32bit production AhsayUBS servers configured with ZFS volumes. Due to
FreeBSD kernel memory limitations on 32bit CPU’s, combined with the
relatively high memory usage requirements of ZFS volumes. AhsayUBS servers
hosting large amounts of data can become unstable and even crash, which
could result in data corruption on AhsayOBS.

4.1.1 AhsayUBS Processor Configuration
From AhsayUBS v2.5.2.0 onwards AhsayUBS supports up to a maximum of 32
virtual processors for both i386/amd64 compatible CPU’s.
In order to comply with the maximum supported virtual processors limit on
FreeBSD, the system administrator should verify the number of virtual
processors enabled on the AhsayUBS machine and apply the correct processor
setup on the machines BIOS before proceeding with AhsayUBS installation or
upgrade.
The maximum number of virtual processors is calculated as:
(No. of sockets) * (No. of cores per processor) * (Hyper Threading).
The following are examples of processor configurations.
Supported Processor Configurations
1. One Socket, Dual-Core Intel CPU, Hyper Threading Enabled
(1) * (2) * (2) = 4 virtual processors
2. Two Sockets, 6-Core Intel CPU, Hyper Threading Enabled
(2) * (6) * (2) = 24 virtual processors
3. Two Sockets, 8-Core Intel CPU, Hyper Threading Enabled
(2) * (8) * (2) = 32 virtual processors
4. Four Sockets, 4-Core Intel CPU, Hyper Threading Enabled
(4) * (4) * (2) = 32 virtual processors
Non-supported Processor Configurations and workarounds
1. Two Sockets, 12-Core AMD CPU, Hyper Threading Enabled
(2) * (12) * (2) = 48 virtual processors
It is recommended the number of cores per CPU be set at 8 on the machine
BIOS:
(2) * (8) * (2) = 32 virtual processors
2. Four Sockets, 8-Core Intel CPU, Hyper Threading Enabled
(4) * (8) * (2) = 64 virtual processors
It is recommended that Hyper Threading is disabled on both CPU’s on the
machine BIOS:
(4) * (8) * (1) = 32 virtual processors
3. Four Sockets, 10-Core Intel CPU, Hyper Threading Enabled
(4) * (10) * (2) = 80 virtual processors
Ahsay Systems Corporation Limited
12
(October 17, 2013)
Ahsay Universal Backup System
Administrator’s Guide
We back up your business
It is recommended that Hyper Threading is disabled on both CPU’s and the
number of cores per CPU be set at 8 on the machine BIOS:
(4) * (8) * (1) = 32 virtual processors
WARNING:
If AhsayUBS is installed on a machine where the number of virtual processors
configured exceeds the maximum supported value of 32. This will cause
FreeBSD to become unstable and crash, which could result in data corruption
on AhsayOBS.
4.2 Installer Media Requirements

- Description (Optional): Your customized message to describe the UPS
connection.
- Shutdown mode: The AhsayUBS shutdown sequence will be trigged by
one of the following UPS power events:
 UPS reaches low battery: UPS runs on battery and the battery level
is low. The low battery alert percentage is defined by the UPS
driver.
 UPS goes on battery: UPS runs on battery (i.e. A.C. power supply is
disconnected in UPS) and shutdown sequence will be started after
the countdown defined in ‘Shutdown timeout’.
- Shutdown timeout: The countdown time (default: 300 seconds) to
shutdown AhsayUBS when [UPS goes on battery]. This option is
available only when the [UPS goes on battery] option is selected in the
[Shutdown mode]. The timeout should NOT be larger than battery
discharge time.
- Email notification: Send email to addresses defined by the [To email] in
the [General Email Settings] when the UPS changes its status [ On Line
Power / On battery ] or the UPS triggered the AhsayUBS shutdown
event. Whenever the email notification is enabled or disabled, power
event will always be logged to the system log in page [Information] >
[System Logs].

8.2.1.6.3 Device List
The page lists the serial and USB device path in the system. The connected
device path pattern for serial device and USB device are “/dev/ttyu*” and
“/dev/ugen*.*” respectively. Since some other USB devices could be
connected to the system, it is suggested to connect the system to UPS by
serial port. Once the appropriate device path is found, administrator may
copy the full path and fill it in the [Port Device Path] field in the [UPS
settings].
8.2.1.7 SNMP
SNMP (Simple Network Management Protocol) is a protocol defined for
managing the computer devices such as servers, workstations and desktop
etc. through IP networks. The software which monitors and configures the
devices in the network is called NMS (Network Management Server). When
a SNMP agent daemon is enabled in the AhsayUBS, the AhsayUBS
administrator may monitor the system status such as performance of CPU,
memory, disk and network with a proper setup NMS from a remote
machine.

The AhsayUBS has been bundled with the FreeBSD SNMP agent ‘bsnmpd’
daemon which supports up to SNMP v2c standard. The functions of this
daemon include:
 report OID object value upon SNMP query from the NMS via UDP port
‘161’.
 send traps to the NMS upon defined events in the AhsayUBS.
It is better for the AhsayUBS administrator to install a ‘bsnmpd’ supported
NMS for communication.
Here are the SNMP modules bundled with the ‘bsnmpd’ daemon:
 MIB-II
Implements parts of the internet standard MIB-II.
 Netgraph
Enable remote access to FreeBSD Netgraph subsystem.
 Host resources
Implements the HOST-RESOURCES-MIB as standardized in RFC 2790.
 UCD-SNMP-MIB
Retrieve system performance information and device detail.
The SNMP daemon will be started once the settings are saved in the page
[System] > [Settings] > [SNMP]. SNMP triggered event can be found in the
AhsayUBS system log at page [Information] > [System Logs].
8.2.1.7.1 SNMP Settings
AhsayUBS Administrator can configure the SNMP settings and check the
SNMP daemon status in the page [System] > [Settings] > [SNMP].

8.3.2.2 Advanced Configuration
The fields in this section are listed below:
- MTU: Set the maximum transmission unit of the interface to n, the
default settings is leave to n, default is interface specific (i.e. blank).
The MTU is used to limit the size of packets that are transmitted on an
interface. Not all interfaces support setting the MTU, and some
interfaces have range restrictions.
- Device polling: Device polling is a technique that lets the system
periodically poll network devices for new data instead of relying on
interrupts. This can reduce CPU load and therefore increase throughput,
at the expense of a slightly higher forwarding delay (the devices are
polled 1000 times per second). Not all NICs support polling.
- Type: Select the speed of network from the drop down list.
- Extra options: You can enter extra options for the FreeBSD command
“ifconfig” here. For more information of this command, please refer to
the FreeBSD documentation.
After the configuration is updated, the page is refreshed. If a reboot
message is shown, please click the link [reboot] in the message to reboot
the AhsayUBS for the changes to take effect.
WARNING: Before rebooting the AhsayUBS, please make sure the network
settings (i.e. the IP address and the default gateway) in the above page(s)
are correct. Otherwise, the AhsayUBS may be UNREACHABLE by the

i. System Storage – This is a core storage volume, which is created
during AhsayUBS installation. The system storage contains AhsayUBS
system files. Therefore, it cannot be removed or unmounted when
AhsayUBS is running.
ii. Additional Storage – can be added when the LSFW storage has run
out of space. It is used for storing more backup user account data. As
additional storage are not core storage volumes. They can be removed
or unmounted when AhsayUBS is running.
Details of the storage model in AhsayUBS can be found in the section
[AhsayUBS Storage Concepts].
Under this page, volume information will be shown and the actions can be
done include:
i. add or remove an additional storage
ii. mount or unmount an additional storage
iii. filesystem check on a volume
iv. rebuild degraded LSFW or additional storage inside this AhsayUBS.

icons:
Healthy
The volume is healthy.
Degraded
The volume is degraded. One or more providers (block
devices) of the volume are missing though the volume can still
be used. The volume can become healthy again with a rebuild
after replacing the missing providers. For details, please refer
to the [Troubleshooting] section.
This state will occur after the provider is replaced in the
volume. After rebuilding completed, the status will become
healthy again. The rebuilding state will not affect the read or
write operation of the volume.
The volume is not available. It is better to suspend all I/O
activity before the volume has undergone further damage.
The volume is missing. It cannot be accessed by the
AhsayUBS. It may be caused by:
 The volume is exported.
 The local storage is disconnected.
For details, please refer to the [Troubleshooting] section.
The corresponding remote disk’s connection is lost. Please

additional storage will be displayed.
Additional Storage can be added when master storage LSFW runs out of space.
Once created, the additional storage can be used for storing more user
accounts data and their backup snapshots of AhsayOBS & AhsayRPS in this
AhsayUBS.
Supported types of the Additional Storage in AhsayUBS:
i.
ii.
iii.
Modular Storage:
 Supports one or multiple physical block devices for building RAID0,
RAID1 and RAIDZ in ZFS from local storage.
 Supports one remote disk (i.e. iSCSI target) to build a RAID 0 ZFS
remote storage.
Expandable Storage: Created with an iSCSI initiator session and hardware
RAID volumes. One iSCSI initiator session (one provider) can support
creating an expandable storage only. Since iSCSI target / hardware RAID
volume can be expanded, the entire disk will be consumed by a single
ZPOOL. The creation of the expandable storage will not be supported in
the current and further releases of AhsayUBS.
Optional Storages (previously named Optional Labelled Device) in UFS
format created in the previous releases of AhsayUBS are also supported,
but the creation of new UFS format Optional Storage is not supported as
of AhsayUBS v2.1.0.0

8.4.4.2 Additional Storage(s) in Disconnected State
The additional storage DISCONNECTED state will only appear in the volume
which is created on a remote disk (i.e. iSCSI initiator session). This states that
the addition storage corresponding remote disk provider (i.e. iSCSI initiator
session) is disconnected from the AhsayUBS.
In order to identify disconnected additional storage, an additional schedule job
has been added to AhasyUBS. When any additional storage has been detected

in disconnected state, the following actions will be taken in order to prevent
further loss of data:
 Service stop and prohibit the service start of the following services:
o AhsayOBS & AhsayRPS
o Share OBSR
 The enabled additional storage volumes will remain mounted. The
system will wait for iSCSI initiator reconnection. In case the iSCSI
initiator exits due to session timeout, AhsayUBS administrator may
create another iSCSI initiator sessions by the ‘Retry’ button at page
“Storage > iSCSI”.
 Email will be sent to AhsayUBS administrator (The ‘To email’ defined in
the ‘General email setting’).
At this stage,
 the corresponding remote disk’s (i.e. the iSCSI initiator session)
network connection to this UBS machine is lost.
 though the corresponding additional storage is still mounted, the data in
this volume cannot be accessed nor written anything to the storage.
To fix the problem, login the AhsayUBS WebAdmin
 Alert dialog contains the disconnected additional storage and their
corresponding iSCSI initiator information will be shown after AhsayUBS
WebAdmin login.
 The lost of iSCSI connection may result from network connectivity issue.
Try to use “Network > Ping / Traceroute” tool to test if the iSCSI target
host is reachable. After resolving the network issue, the iSCSI target
host will be reconnected with AhsayUBS machine and the data in the
additional storage can be accessed again.
 After resolving the additional storage disconnection issue, service start
will be allowed for the following services. Please refer to the section
[Backup Server] for details.

8.4.5 Additional User Storage Migration
8.4.5.1 Introduction
As of AhsayUBS v2.7.0.0, additional user storage migration from an old
AhsayUBS machine to new AhsayUBS machine is supported.
AhsayUBS additional user storage migration is performed using a UNIX shell
script. The migration process only supports additional user storage volumes,
the system storage (firmware) volume, i.e. FreeBSD and AhsayOBS binaries
are not supported. After a successful migration, the data on the file system
can be used by the AhsayOBS service on the new AhsayUBS server.
Supported Hard Disk Interfaces:

Local: IDE, SCSI, SATA, Hardware RAID


Foreign: iSCSI
Supported Additional Storage Types:
The storage migration script only supports the migration of additional storage
with only one provider (single hard disk). The storage volume to be migrated
must in a healthy state. The support storage types include:




Optional Storage (GPT Partition 6 with UFS)
Expandable Storage (No Partition with ZPOOL on entire disk)
Modular Storage with CLOG only (GPT Partition 7 with ZFS)
Modular Storage with CLOG & SLOG (GPT Partition 11 / 13 with ZFS)
WARNING:
1. AhsayUBS system storage (esosfw/eslsfw) is NOT supported by the storage
migration shell script.
2. After volume migration the original storage label in the migrated storage
volume will be updated. The previous AhsayUBS installation will no longer be
able to use the migrated storage volume.
3. Since the profile.ini file (/ubs/conf/profile.ini) will be updated by this shell
script. DO NOT perform any add or remove storage operations via the
AhsayUBS webadmin console when the volume is migration is in progress.
8.4.5.2 Storage Migration Procedure
Assumptions
1. The volume to be migrated is in a healthy state.
2. There are no disk errors prior to migration.
3. SSH is enabled on AhsayUBS

8.5.2 Tape Utility
8.5.2.1 Introduction
The AhsayUBS administrator may backup selected user accounts to tape
cartridge while the backup server remains online. The AhsayOBS user account
data can be restored to the AhsayUBS server either to the original or an
alternate location. The tape backup/restore operation is managed from the
AhsayUBS webadmin console.
8.5.2.1.1 ‘User Home’ setting in the Backup Server
AhsayOBS stores all user accounts under the ‘User Home’ directories. When a
new user account is being created, AhsayOBS will create a directory with the
user’s login name under the assigned ‘User Home’ path. The created user
directory is used for storing user configuration and backup files. The list of
user names can also be found from the AhsayOBS WebAdmin.
The ‘User Home’(s) setting can be viewed from the AhsayOBS WebAdmin
[Server Configuration] page:

8.5.2.1.2 Tape Device and Tape Standards
FreeBSD provides full support for SCSI-I, SCSI-II and SCSI-III tape drives. As
AhsayUBS is built on top of the FreeBSD operating system, SCSI tape drives
are therefore supported. The ‘sa – SCSI Sequential Access device drive’ will be
used for accessing the tape device.
Note: Tape libraries and tape changers are NOT supported by AhsayUBS.
The following tape drive standards are supported by FreeBSD. Each tape
standard has its own maximum data capacity and transfer rate. For each
hardware type and supported tape standard, the cost of the tape drive and
tape cartridge varies.
I. DAT - Digital Audio Tape (format: DDS - Digital Data Storage)
II. DLT - Digital Linear Tape (halted development since 2007)

Before purchasing a tape drive, please consult your hardware vendor to
confirm compatibility of the device with the FreeBSD operating system.
The following factors should also be considered:
i.
Compatible hardware interfaces with the AhsayUBS machine for
connecting tape drive.
ii. Tape cartridge capacity for storing user data.
iii. Tape transfer rate.
Note: Tape backup/restore on AhsayUBS has been developed and
tested using a DELL PowerVault LTO-4 tape drive, connected to a DELL
6GB HBA SAS controller using 800GB LTO-4 tape cartridges.
8.5.2.1.3 Tape Backup/Restore Process via the AhsayUBS WebAdmin
An AhsayUBS administrator may backup/restore user home data to/from tape
cartridges via the AhsayUBS webadmin console [Backup Server] > [Tape
Utility] menu option.
Before using the [Tape Utility] option, the tape device must be:
1. Connected with the AhsayUBS server.
2. The tape device must be powered on.
3. AhsayUBS must be able to detect the tape hardware. The identified
tape device will be shown in the [Backup Server] > [Tape Utility] >

In most cases, a single tape cartridge will not be sufficient to store all the data
on a user home volume. During a backup operation if the current tape
cartridge is full, AhsayUBS will prompt for a new tape cartridge to be inserted
into the tape drive. For tape restore operations if the data spans more than
one tape cartridge, AhsayUBS will prompt for the insertion of the next tape
cartridge.
If a tape device is not supported or no tape drive is installed on the AhsayUBS
machine, the AhsayUBS webadmin [Backup Server] > [Tape Utility] menu
option will be disabled, the following message “The system cannot find any
supported tape device.” (As shown in the following example).

Notes:
1. Tape cartridges must be managed, handled, and stored properly. Proper
care by trained staff is important to prevent inadvertent errors and media
damage.
2. Only ONE tape backup/restore process can be started at a time.
3. Only ONE tape cartridge can be used for tape backup/restore process at a
time.Therefore, manual tape cartridge replacement is required when the
current tape cartridge full.
4. Only ONE AhsayOBS ‘User Home’ path can be selected for backup at a time.
5. Only CONSECUTIVE tape cartridge can be used for restore.
6. Any corrupted or damaged intermediate tape cartridge(s) will result in the
failure of the entire tape restore process.

Appendix J – Identifying Physical Local Block
Devices on AhsayUBS
Method 1: Serial Number
The “Serial Number” is the unique identifier for a block device. Thus, the block
device can be found physically in the machine by its serial number.
Here are the steps to look for the serial number in the AhsayUBS WebAdmin:
1. In the page [Storage ] > [Summary], click on the block device icon
‘ ’ that looking for.The page then will be redirected to [Storage] >
[Summary] > [Block Device Information].
2. If the “Serial Number” can be retrieved by the block device, the row
“Serial Number” will exist in the table.
Method 2: Device name
If a block device is connected to a specific controller e.g. 'ad' for ATA or 'da' for
SCSI. The connector will be named and ordered starting from 0, e.g. ad0, ad1,
da0, da1 … etc. Therefore, the block device can be identified according to the
controller name and the connector number.
To look for the device name, please follow the steps below:
1. In the page [ Storage ] > [ Summary ], click on the block device icon
‘ ’ that looking for. The page then will be redirected to [ Storage ] >
[ Summary ] > [ Block Device Information ].
2. The “Device Name” exists in the information table.

CPU Statistics
The following attributes provide measure to CPU usage in number of ‘ticks’
(typically 1/100s).
On a multi-processor system, the counter values are cumulative over all CPUs,
so their sum will typically be N*100 (for N processors).

em
the last minute.
This object may sometimes be implemented as the
combination of the ‘ssCpuRawWait(54)’ and
‘ssCpuRawKernel(55)’ counters, so care must be taken when
summing the overall raw counters.
ssCpuRawUser The number of ‘ticks’ spent processing user-level code over
the last minute.
ssCpuRawIdle
The number of ‘ticks’ spent idle over the last minute.
Disk I/O Statistics

Appendix L - MIB Browser
MIB Browser allows administrators to load MIB definition files and connects to
SNMP enabled network devices and applications. Some MIB browsers provide
both text view and table view for the retrieved MIB values. In the following, we
are going to demonstrate with the ‘iReasoning MIB Browser Personal Edition’.
(http://ireasoning.com/downloadmibbrowserfree.php)
1.
The MIB Browser GUI includes the following views:
- Address and Advanced (menu bar, for SNMP agent connection
configuration)
- MIB Tree (top left panel, presenting the supported MIB entities)
- MIB Description (bottom left panel, presenting the MIB entity detail)
- Result Table (top right panel, presenting the OID query result)

By selecting specific OID entities, the SNMP ‘Get’ operation will retrieve the
selected OID values. The OID entities will be mapped with the
corresponding name defined in the MIB files. For example, we may retrieve
the all entity values under the OID ‘iso.org.dod.internet.mgmt.mib2.system’ via the MIB Browser.
On the other hand, the MIB Browser may walk through the entire MIB Tree
by the SNMP ‘Walk’ operation. All OID entities will be retrieved from the
SNMP agent. If the corresponding MIB definition file is not found, the
retrieved OID will be displayed in numeric format.

Some OID may exist as customized entry type. Multiple instances of entity
value may exist under certain OID. For example, a system may contain
multiple disks that each disk could be indexed by a unique index value. In
such case, the MIB Browser may provide the ‘Table View’ that all supported
entity values can be presented in table format.
From OID ‘iso.org.dod.internet.private.ucdavis.dskTable.dskEntry’, we may
retrieve the system disk detail in table view with the corresponding
‘dskPath’, ‘dskDevice’, ‘dskTotal’, ‘dskUsed’ and ‘dskPercent’ entity values.
