MSA2050 Replacing failed disk

AB_FIDA — Fri, 28 Feb 2020 11:24:09 GMT

Hello ALL,

I have a MSA 2050 storage equipped with 10 SAS 1,2 TB 12G 10K disks, RAID5 configuration without spare disk.

Unfortunately, last week a disk gone in a wrong state because electric lines problem and message was about possible invalid metadata.

Steps were ask for disk replacemnt by HP and a new disk order for spare disk role; first action was add spare disk and assign it that role and it seems went well.

Next, iI replace the wrong disk with the new one from HP but no activity starts and that disk appear as "available"..... so what happened on my storage, at the end i can see just only 9 disks up and running but how can I put into diskgroup the missing disk ?

Regards

Alberto

Can you please provide below outputs (please mask the serial numbers),

show disk-groups

show disks

If the replaced drive shows as "Available" which means still its not configured as Spare drive. So suggest you to follow the below steps and configure Global Spare,

To add global spares
1. In the Pools topic, select Action > Manage Spares. The Manage Spares panel displays.
2. In the Add New Spares section, click on available disks to select them.
3. Click Add Spares. The system updates the global spares and a confirmation panel displays.
4. To close the confirmation panel, click OK.

After you configure Global Spare then only disk-group rebuild will start.

Hope this helps!

Thanks for sharing this data.

We can clearly see that VDG named DG-R5-1200 made with 9 drives only and not with 10 drives. Your VDG state shows as FTOL which means it's perfectly alright.

It seems drive at location 1.2 was never part of the VDG named DG-R5-1200. May be it was configured as Spare drive only.

Next job is to configure 1.2 also as Global Spare.

Hope this helps!

Thank you for your help.

I think there was a misunderstanding with HPE support assistant because she notice us about no designated spare disk in our configuration whereas it was the one in wrong state.

Hi there, I have different disk-group with different drive capacities and RAIDs. one disk-group is made up of 900 GD drives on RAID5 (say, gpa-R5-9), another is made up of 6000 GB drives and RAID5 (say, gpb-R5-6) , and another is made up of 2.4 TB drives and RAID5 (say, gpc-R5-2.4).

gpa-R5-9 now has one 2.4 TB drive while the rest of its drives are 9000 GB.

We have 600 GB and 900 GB Global spare (newly configured) with none for 2.4 TB. There is also one available 9000 GB (which I intend to make a Global spare as well).

My suspicion is that the 2.4 TB drive in gpa-R5-9 was a Global spare and kicked in there since it was the only global spare equal/greater than 9000 GB.

How do I remove the 2.4 TB drive from gpa-R5-9 and let it failover to the new 9000 GB Global space and then configure the 2.4 TB drive as a Global space? Going through the Wed UI, there is no feature to from a drive from a group. Your expert reply will be appreciated. Thank you,
