Managed System for SAN Storage Agent User's Guide


Step 1. Network

The server system and the client systems must be attached to the SAN along with appropriate storage devices. The server system and the client systems must also be connected by means of a LAN.

The Managed System for SAN feature requires specific levels and models of hardware and software. Ensure that your system configuration meets the hardware and software requirements for the SAN setup. See the Web site, http://www.tivoli.com/support/storage_mgr/san/overview.html, for details.

Note:
If you will be using Tivoli storage agent with disk media, you must have installed Tivoli SANergy Version 2.2 on the applicable machines. See Figure 3 for possible Tivoli SANergy configurations. See the Tivoli SANergy Administrator's Guide for details.

Important: If your environment includes an IBM LTO Ultrium tape drive and your storage agent will be located on a computer using Windows 2000, you must verify and possibly change the host-bus-adapter (HBA) setting. For most HBA's this value is located in the MAXIMUMSGLIST registry setting. The MAXIMUMSGLIST value on the storage agent must be equal to, or greater than HEX 41 (decimal 65) or a data integrity error may occur. To verify or change the current registry setting perform the following:

  1. Edit the Registry
  2. Click HKEY_LOCAL_MACHINE | SYSTEM | CurrentControlSet | Services |(vendor HBA name*) | Parameters | Device
    Note:
    For (vendor HBA name*) in the previous description, substitute the vendor's device name for your environment (for example, for the Qlogic 2200 and 2300, the name appears as Ql2200 and Ql2300 respectively). If your vendor's HBA name does not appear as a registry entry, contact the HBA vendor to determine the location of the setting and then verify that the setting is correct.
  3. If the setting's hex value is 41 or higher, verification is complete. Close the registry editor, and continue with the storage agent installation and configuration procedure. If this value is less than 41, change the value to 41 or higher, then save the new registry entry, close the registry editor, and continue with the storage agent installation and configuration procedure. Make sure that all Windows 2000 storage agents located in your LAN-free environment meet this criteria.
