About EMC Navisphere server software
The EMC server-based software listed below is available on Powerlink and on the server support CD that shipped with your storage system or your upgrade kit (for upgrading AX4-5 series or AX series systems to Navisphere Manager).
For information on the server software supported with your CLARiiON
® storage system and the minimum FLARE

About the Navisphere Storage System Initialization Utility
For Fibre Channel storage systems, use the Navisphere
® initialization utility to discover storage systems and set network parameters (IP address, subnet mask, and default gateway). In addition, for iSCSI storage systems with iSCSI data ports attached to Windows servers, use the utility to set network parameters for these ports.
For CX series storage systems, an authorized service provider must install and run the initialization utility.
You can run the initialization utility from the server support CD or you can install it on a server or other host such as a Navisphere off-array management station. The only requirement is that the host be connected to the same network subnet as the storage-system management ports.
About the Navisphere Host Agent
The host agent registers the server’s host bus adapter (HBA) with the attached storage system when the host agent service starts. This action

sends the initiator records for each HBA to the storage system. Initiator records are used to control access to storage-system data.
The agent can then retrieve information from the storage system automatically at startup or when requested by Navisphere Manager or CLI.
The host agent can also:
Send operating system drive mapping information to the attached
CLARiiON® storage systems.
Monitor storage-system events and notify personnel by email, page, or modem when any designated event occurs.
Retrieve LUN world wide name (WWN) and capacity information from Symmetrix® storage systems.
About the Navisphere Server Utility
The server utility allows you to perform the following functions:
Update server information to the storage system
— Lets you send the server name and IP address to the storage system and, if needed later on, allows you to update or view this data.
Verify server high availability (HA)
— Lets you determine if the server is configured for high availability (HA) by verifying that the server has at least one connection path to each storage-system
SP, and that PowerPath
® or some other failover software, such as
VMware native, DMP, PV Links, or HP native failover for 11iV3 is running. The utility does not detect any other native failover software, such as Sun StorEdge Traffic Manager or Linux native multipath (MPIO).
Use the snapshot feature (Navisphere Express only)
— On storage systems with Navisphere Express, you can start and stop a snapshot on the source server (server assigned to the source virtual disk or source LUN), or you can allow or remove access to the snapshot by the secondary server (server assigned to the snapshot).
On AX4–5 series storage systems with Navisphere Manager, you cannot use the server utility to manage snapshots. Instead, you must install and use the admsnap utility.

EMC CLARiiON Server Support Products for Linux Servers Installation Guide
You can run the Navisphere Server Utility from the CD or you can install it on the servers that are connected to the storage system. We strongly recommend that you install the utility on each server that is connected to the storage system.
About the Admsnap Utility
The Admsnap Utility is an executable program that you can run interactively or with a script to manage SnapView
® clones and snapshots. The Admsnap Utility resides on the servers connected to the storage system with the SnapView driver installed.
Use admsnap commands to:
Scan for new storage devices
Make storage devices inaccessible to the server operating system
Flush cached data to disk
List current snapshot devices
Map and unmap to a SnapView session
Start and stop a SnapView session
If you upgraded your storage system to Navisphere Manager and want to manage snapshots, you must use the SnapView software and the Admsnap
Utility. For more information on SnapView and admsnap, refer to the
Navisphere Manager help and the EMC SnapView Command Line Interfaces
Reference.
About the Navisphere CLI
The CLI complements, or is an alternative to Manager. It provides a command line interface for storage-system management, including storage provisioning, status and configuration information retrieval, and control. You can use the CLI to automate management functions through shell scripts and batch files. For more information, refer to the
EMC Navisphere Command Line Interface (CLI) Reference Guide.
