Re: Wrong disk size during replacement

wojciech_bajorek · ‎2010-02-26

Hi,

I have FAS270 with 146GB FC disks. Unfortunately one disk failed and I provided a replacement - exact model.

Drive was used somewhere else and had data on it. When I inserted the disk, system rejected it and marked as failed (unknown data on disk).

I managed to bring it as a spare with disk unfail -s <disk_id>, however disk has lower size than other disks (0b.26).

I tried with disk zero spares command, but that didn't change anything.

Sysconfig -r output:
Aggregate aggr0 (online, raid_dp) (block checksums)
Plex /aggr0/plex0 (online, normal, active)
RAID group /aggr0/plex0/rg0 (normal)

Spare disks

RAID Disk       Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks)    Phys (MB/blks)
---------       ------ ------------- ---- ---- ---- ----- --------------    --------------
Spare disks for block or zoned checksum traditional volumes or aggregates

What is really strange in here is that TYPE = ATA, while the rest of the disks = FCAL. Why is that so?

What can I do to make this new disk as a real spare?

Thank you in advance.

Hi! Check output of storage show disk and sysconfig -v command.

Maybe you need update Disk Qualification Package file.

https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb50298

http://now.netapp.com/NOW/download/tools/diskfw/

It helps for me.

Thanks for the proposal.

I checked these qual_devices* files on my filer and I what is really strange here is that size of these files is bigger than sizes of the files downloaded from now.netapp.com.

Is this correct? (files on my filer are quite old = 2007)

sysconfig -v output:

26 is the new disk. Any new ideas how to make it visible as the rest of the disks?

What's the source of the disk 26? It shows Hitachi, not NetApp. Are you sure it's the correct disk? If so, maybe you need to update disk firmware.

Thanks,

Wei

It looks like original Hitachi disk:

HITACHI HUS103014FLF210 ULTRASTAR 10K300 147GB 10KRPM 16MB FIBER CHANNEL 40PIN SCA-2 3.5" HARD DRIVE

Of course you can download latest fw pack for drives and manualy update fw (disk_fw_update).

But i think it doesn't help.

If you get this drive from NetApp you need contact with support.

Hi ,

Please try upgrading the Ontap , it should take care of the issue.

This is older so you may have solved it. One thing I noticed... the replacement disk is 512 block, original disks are 520 block.

Can't replace 520B drives with 512B drives.
