Degraded disk group
Hi all,
we have a MSA 2040 SAN and facing an issue with it:
There is a problem with a FRU. (FRU type: disk, enclosure: 1, slot: 10, device ID: 10, vendor: HP , product ID: EG1200JEHMC , SN: info erased, version: HPD3, related event serial number: B1126, related event code: 55)
Disk somehow in "Healthy" state, but group not.
The disk group is not fault tolerant. Reconstruction cannot start because there is no spare disk available of the proper type and size.
- Replace the disk with one of the same type (SAS SSD, enterprise SAS, or midline SAS) and the same or greater capacity. For continued optimum I/O performance, the replacement disk should have performance that is the same as or better than the one it is replacing.
Disk Group is "Degraded" and in CRIT state, also we have 3 disks in "Global Spare", but reconstruction has not started. Could you advise what need to be done?

Re: Degraded disk group
It looks to me dgA02 was created with 12 drives but not sure how many available now. From screenshot right now 10 drives visible but may be other two drives or 1 drives got hide which need to scroll down/up to get visibility. At least from the screenshot it looks like two drives missing.
Please provide screenshots of all 3 Global Spares the way you have given for 1.10
Hope this helps!

Re: Degraded disk group
Thanks for your answer!
I don't really know how was created dgA02. Here is screenshots with whole dgA02 and all disks.
I'm agree that group was created with 12 disks, but how to add it back or assign spare to it? What do you mean "Please provide screenshots of all 3 Global Spares the way you have given for 1.10", what I should do to provide this info?
Thank you again!

Re: Degraded disk group
First take downtime and go for rescan option because IOs will be halt for few seconds.
If this also not help then try rebooting Controller A
Hope this helps!

Re: Degraded disk group
It looks like 1.10 having issue as well.
What is the status of dgA02 now ?
Do you see any rebuild progress bar now ?
To perform a Controller restart if required,
1. Perform one of the following:
In the banner, click the system panel and select Restart System.
In the System topic, select Action > Restart System.
The Controller Restart and Shut Down panel opens.
2. Select the Restart operation.
3. Select the controller type to restart: Management or Storage.
4. Select the controller module to restart: Controller A, Controller B, or both.
5. Click OK. A confirmation panel appears.
6. Click Yes to continue. Otherwise, click No. If you clicked Yes, a message describes restart activity.
Hope this helps!

Re: Degraded disk group
It's always suggested to have valid data backup before you try Controller restart or any other operation. I hope before you try anything you already taken data backup as best practice.
Hope this helps!

Re: Degraded disk group
We have backup for all VMs running on this storage, but anyway (in normal) I'm able to restart controllers (one after another) without any issue?
Group still degraded:
Maybe somehow I'm able to add disks to existing group? Cause number of disks is 12, but actually only 11 are in Up state.
