I have netapp v3140 running on ontap 8.1.2 and ibmDS4800 under the vseries.
We are seeing HA capability getting disabled and then within 1 min being enabled on its own.
After referring to the autosupport/debug logs it shows the command timeouts:
[fci.device.quiesce:debug] Adapter <XXX> encountered a command timeout on Disk <XXX> retry: 0 Quiescing the device.
[fci.device.timeout:debug] HBA <XXX> encountered a device timeout on Disk device <XXX> retry: 0
[scsi.cmd.abortedByHost:debug] Disk device <XXX>: Command aborted by host adapter: HA status 0x4: <XXX>
[fci.device.timeout:debug] HBA <XXX> encountered a device timeout on Disk device <XXX> retry: 0
[scsi.cmd.abortedByHost:debug] Disk device <XXX>: Command aborted by host adapter: HA status 0x4: <XXX>
IBMDS4800 does not provide any statistics to investigate the host interface ports which are providing connectivity to the netapp storage via san switch. San switch does not show any errors apart from the c3frames discards.
Anyone has experience with this setup ?? please suggest...
