Degraded Disk on 3PAR

Hello,

we had a failed HDD on HPE 3par 7200.

once replaced, it has been degraded again.

we were trying to dismisspd and but it is giving that the drive still having chunklets.

we triggered showpdch -from ID, and it is giving 411 chuncklets.

Do you have any way to move all these chunks in one command? noting that we executed movepdtospare, it is pointing that is doesn't have any chunks, but in fact, it is. see below:


HP-3PAR cli% movepdtospare -dr 168
Are you sure you want to move the PD to spare?
select q=quit y=yes n=no: y
There are no chunklets to move.

HP-3PAR cli% dismisspd 168
Error: Pd id 168 is referenced by chunklet 23:338
HP-3PAR cli%

 

Please help, your support will be much appreciated.

Re: Degraded Disk on 3PAR

Please see the below and advise what to do in case you faced the same problem:

 

HP-3PAR cli% movech -perm -ovrd 136:0
Are you sure you want to move the chunklets?
select q=quit y=yes n=no: y
Error: Disk 136 chunklet 0 is not in use.
HP-3PAR cli% showpdch -spr 136
No chunklet information available.
HP-3PAR cli% removespare 136:a
Are you sure you want to remove spares?
select q=quit y=yes n=no: y
No spares removed
HP-3PAR cli% dismisspd 136
Error : Pd id 136 is referenced by chunklet 0:339

Re: Degraded Disk on 3PAR

Hi LElie,

From the output errors, it looks like the failed PD is vacated, and chunklets are in spare,

And you cannot dismiss the PD, when the chunklets are referenced.

You may use the below command to relocate these chunklets,

cli% moverelocpd -f -partial -p -tc_gt 0

You can run this command in Dry run mode to check the chunklets it will move as below,

cli% moverelocpd -dr -partial -p -tc_gt 0

If the newly replaced PD is also defective, you may replace it again, and run "servicemag resume" also, and then dismiss the PD.

Hope this helps,

Regards,

Re: Degraded Disk on 3PAR

Hello N_JK,

 

Thanks for your reply.

Whenever we are trying to initiate the command below, we are getting an error.

Please see:

HP-3PAR cli% moverelocpd -f -partial -p -tc_gt 168
Move -State- -Detailed_State-
204:1065-204:273 failed duplicate_dest
204:1066-204:273 failed duplicate_dest
0:339 failed spares_not_found
0:522 failed spares_not_found
0:523 failed spares_not_found
0:524 failed spares_not_found

 

 

the list is too long to post it here.

means the command failed and didnt work as expected.

Can you have any other tip so we can apply it?

 

Regards,

Elie Lteif.

Re: Degraded Disk on 3PAR

Hi Eile,

 

This condition could be due to the failed disk on the array.

 

You may replace the disk and run servicemag resume instead.

 

Thanks and Regards,
