B-Series Disk details RAID rebuild issues after disk removal

[raoulst]

Hi,

after removing and reinserting one disk from a RAID-1 on our B-Series blades for testing, the disk details for the reinserted disk will not be fully shown.

Only the disk itself gets detected and "Presence" shows "equipped" (see attached screenshot).

It also doen not look like the RAID would be rebuilt.

So does anyone know how to:

* Get all disk details again.

* (Automatically) reinitialize the RAID rebuild.

* Monitor the RAID status.

* Be notified of a RAID failure.

Just forgot one thing:

* Monitoring the disk status would also be nice.

Ralph,

Yeah we are aware that UCSM doesn't report that info.

Until we can get that info into UCSM you can try and use the MegaRAID tools from LSI to monitor the array.

They have tools for Linux and Windows that will allow you to monitor the array status.

What OS are you running?

Hi,

not very happy with the fact that UCSM doesn't display a disk or RAID status.

Any chance that we might see that in an upcoming release?

We are using ESX 4.0 U2, RHEL 6 and W2K8 R2.

Hope that MegaRAID tools would work and can be queried by SNMP (or so).

I found out how to get the disk data again and get rid of the following warning that obviously comes with not getting the disk details:

Description:
* Server sys/chassis-1/blade-6 does not fullfill Service profile vmw66 due to incompatible-number-of-local-disks
* ID: 828447
* Cause: server-failed
* Code: F0337

Solution -> re-aknowledge the server...

Any chance that this might be a bug (in 1.4.1i)?

edit: Seems that has been around for a while:
