Unity rebuild

Question

HI there ...

Does anybody know about Unity Rebuild estimate time and Rebuild Priority ( if there is ,,, ) ?

Or how to check rebuild status ( completed % some kind like getdisk cmd in VNX ... ) so that I can guess how log will it take to complete ....

thanks !

Hi all,

You can use the service command "svc_diag -s sas"

Probably best to redirect the output to a file as the output is extensive.

Once you have the output, locate this section:

FBECLI> sepls:

Type Obj ID ID Object Info Lifecycle State Downstream Drives

Objects

------------------------------------------------------------------------------------------------

Here you will see the rebuild status and % complete. Example from my lab below.

In this case, the pool was originally built on 0_0_0 0_0_1 0_0_2 0_0_3 0_0_9

I removed 0_0_9 to show you the rebuild process. You can see 0_0_4 took over and the RG is currently rebuilding.

The current percentage is shown next to the drive that is being rebuilt, in this case, 0_0_4:

FBECLI> sepls:

Type Obj ID ID Object Info Lifecycle Downstream Drives

State Objects

------------------------------------------------------------------------------------------------

RG 0x170 :368 8 RAID5 READY 363 364 365 366 367 0_0_0 0_0_1 0_0_2 0_0_3 0_0_4 (REB:8%)

Hope this helps.

Was there ever an answer to this? There does not seem to be any visability on the Unity RAID arrays, or rebuilding when a drive fails. I have had two drives fail on the same DAE within a week. It would be nice to know what is going on with the arrays, and to see if data is safe. This product is WAY to dumbed down for enterprise use.

Have you enabled Alerting via EMail or syslog ? Other options are to use the svc_ commands or look at the logs

Thanks Andre, yes this is a great help. A shame it isnt visible from Unisphere, but this is what I was after. Cheers, Paul

Hi Paul,

I am glad you found this useful.

I would encourage you to raise a PER (Product Enhancement Request) with the help of you local representatives if you think the product is missing functionality.

Also, if this answer helped, please mark the thread as resolved / answered so it may be used in the future as reference for other community members.

Thanks

Grepping for 'REB' seems to work via SSH and saves you the step of writing to a log and searching... 18:04:05 service@(none) spa:~> svc_diag -s sas | grep REB RG       0x2c5 :709   29    RAID6           READY ERRVR   0% 701 702 703 704 705 706 707 708   1_4_0  0_4_8 (REB:62%)  1_4_2  1_4_3  1_4_4  1_4_5  1_4_6  1_4_7 18:04:39 service@(none) spa:~>
