Good afternoon, Dear forum users.

I ask you to help in solving one issue, we have 3PAR 8450, one day we removed the discs from the basket, but the procedure was not carried out safely, they just pulled it out. After a situation arose that these disks are displayed in the failed status. We tried to transfer chunklets with the command "movepdtospare -f -vacate -nowait", but the error "src_set_invalid" occurs. We tried to disconnect the disk "dismisspd", but the system informs that the disk is in use "Pd id is in use". I ask you to help, how is it possible to delete these disks?

those chucklets are usually spare (based on number and size). Could be that PD11 was pulled first and started to rebuild on spares from PD10 .. which again was pulled, while the reference to PD10 still exists on those chunklets.

Look at showpd -c to see if anything is used. If so, check with showpdch -mov to see what needs to be moved and move them manually with movech.

Thank you for your prompt reply. Two disks were ejected at the same time, tried showpdch -mov but 3PAR does not display these PDs. Tried to manually migrate chunklets, but I get the error "Error: chunklet couldn`t be relocated. Ld raid set failed". If I understand correctly these chunklets belong to .srdata sections. What is the correct way to delete information about disks that no longer exist?

What does checkhealth -svc detail say?

Okay. So it doesn't seem like any LDs are failed.

What would this command give as output:

movech -perm -ovrd 10:3564

And what does this give as output:

servicemag status

With LDs everything is fine, if I understand correctly chunklets were reserved in the system, and the problem lies precisely in displaying PDs with a failed state. The output of the commands is shown in the screenshot. There is no data on 3PAR, is it possible to re-initialize?

I would cancel the servicemag on PD10. I'm assuming you have no intention of re-adding a drive to that slot.

What does this command provide:

movech -perm -ovrd 11:3561

Servicemag canceled all operations, when trying to transfer chunklets from 11 PDs, the same error occurs as with 10 PDs
Error: chunklet 11: 3561 couldn't be relocated. ld raid set failed
