Log errors

[mikep]

Looking again at the logs I have this error, that was causisng VMs on that hypervisor went to RO:

Dec 8 09:53:56 [kern.info] kernel: [978191.413459] iscsi-scst: ***ERROR***: Connection with initiator iqn.1994-05.com.redhat:eba5969b759d unexpectedly closed!

But this is before the I/O error at:

2011/12/08 09:56:15|I/O Errors detected on unit S004. The unit requires your urgent attention in order to decrease the risk of data loss.

Is the same error? second one was reported later but is the root of the first one?

Aso, in that link says:

Select Repair File System on LV (Logical Volumes)
Please note: when running file system repair the volumes will be unmounted and the shares not available for use.

This means all SAN volumes or just the one to be repaired?

For your question about :
Dec 8 09:53:56 [kern.info] kernel: [978191.413459] iscsi-scst: ***ERROR***: Connection with initiator iqn.1994-05.com.redhat:eba5969b759d unexpectedly closed!

This erros means that the connection between your initiator and your system is closed, and as you can see "unexpectedly" that means your disk is stop working, or the RAID controller hangged or report errors, and finding such error with your previous erros note is not strange, as the preivous erros can close the connection, so this error message can appear.

For your question about:
"Select Repair File System on LV (Logical Volumes)
Please note: when running file system repair the volumes will be unmounted and the shares not available for use."

Well this will affect all the volumes that your DSS is dealing with.
