Cannot Connect to Storage (no further info...)

Hi,

Just wondering why vCenter doesn't display any more info about the storage connectivity alarm than the attached? How do I find which storage it's having problems connecting to?

Thanks for any help.

The logs tell the story of which datastore and path(s) failed.

[esx.problem.storage.redundancy.degraded] Path redundancy to storage device naa.60060160841039008b428b7a1d38e411 degraded. Path vmhba2:C0:T0:L1 is down. Affected datastores: "CT_LUN1_3TB".

it goes on to rattle off more entries.

So your CT_LUN1_3TB lost connectivity to the storage array. The NAA number can be used on the storage array side to uniquely identify which LUN on the array correlates to CT_LUN1_3TB.

Hi,

Is it FC,NFS, ISCSI or local storage.

Hi,

Sorry for the delay.

- Mix of iSCSI and FC

- Yes, all datastores were available on the ESXi host. I couldn't see an issue so whatever it was, it was very brief.

- Logs attached.

Let me know if you need anything else.

Thanks for that. Suppose it only lost one path. Just find it strange that this information isn't available within the client and you have to dig through the logs.

Glad to help.

The information should be available under the hosts "events" section. However depending on how long ago the event occurred it may have rolled off from the view.

Also if you have your alarms configured for storage you will get an email alert with all the information (datastore, path, host ect..) as soon as it happens.
