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.

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.
