A DS4800 SP that runs Windows as a guest operating system should return Not Ready sense data when it is quiescent. Returning Unit Attention might cause the Windows guest to fail during a failover.

Procedure

  1. Determine the index for the LNXCL host type by using the following commands in a shell window.

    Press Enter after each command.

    SMcli.exe ip-addr-for-SPA show hosttopology; Enter SMcli.exe ip-addr-for-SPB show hosttopology

    The following commands assume that 13 is the index corresponding to LNXCL in the NVSRAM host type definitions. If your storage processors have LNXCL at a different index, substitute that index for 13 in the following commands.

  2. Execute these commands for SPA to have it return Not Ready sense data.

    Press Enter only after you enter all commands.SMcli.exe ip-addr-for-SPA set controller [a] HostNVSRAMBYTE [13,0x12]=0x01; set controller [a] HostNVSRAMBYTE [13,0x13]=0x00; reset Controller [a]

  3. Execute these commands for SPB to have it return Not Ready sense data.

    Press Enter only after you enter all commands.SMcli.exe ip-addr-for-SPB set controller [b] HostNVSRAMBYTE [13,0x12]=0x01; set controller [b] HostNVSRAMBYTE [13,0x13]=0x00; reset Controller [b]

    Note:

    If you use the DS4800 Storage Manager GUI, paste the configuration commands for both storage processors into a single script and configure both storage processors at the same time. If you use SMcli.exe, make individual connections to each SP.
