Netapp FAS250 filer broken disk replacement procedure. How?

YHCHEN168 — Thu, 05 Jun 2025 05:57:56 GMT

Dear all,

We have a FAS250 filer that has 7 FC-disk (300GB). The bay 0 disk failed and the system show below error messages when we run "vol status" command:

nas> vol status

Volume State Status Options

vol0 online raid_dp, flex nosnap=on, nosnapdir=on

degraded

root_vol online raid_dp, flex root, nosnap=on, nosnapdir=on

degraded

And below messages are "storage show disk -x" command:

Bay 0 was remove by hand due to the system will halted if Bay 0 disk is remained on slot. We have a used 300GB FC-DISK, it was take out from previous older Netapp filer. Now, can someone help us how to replace failed disk drive(Bay0) from a used disk drive? We have tried to inserted this used disk driver to Bay0, But nothing happen? "aggr status" display:

Hi - when the replacement drive is inserted into Bay0, it will more than likely have old meta data present on the disks.

Run a disk show -v when inserted and the system should show the disk as inserted but not assigned to the system.

Was this disk removed from a HA system?

The disk will need to be assigned to the system and then zeroed, before it will appear as a spare. once allocated as spare, the system should then rebuild the aggr.

disk assign 0b.XX

disk assign all (if you have no other unassigned disks present in the system).

then

disk zero spares

Dear Martin,

Thanks for your reply.

Here is the "sysconfig" command output:

NetApp Release 7.2.4: Fri Nov 16 00:34:57 PST 2007

slot 0: NetApp ATA/IDE Adapter 0a (0x00000000000001f0)

0a.0 249MB

I have try "disk assign" command, but it looks like no "disk assign" options. Maybe it is 7.2.4 version problem ?

Yes this disk was removed from another NAS filer, It should be has old meta data on it. Any though?

Thanks!

Have you tried the CLI in priv set advanced for the disk commands. Can't remember what commands are present that far back for such an old version of ONTAP

Which version of DataONTAP was running on the filer from which this disk was taken?

Re: Netapp FAS250 filer broken disk replacement procedure. How?

YHCHEN168 — Wed, 24 Jul 2013 16:08:45 GMT

Dear aborzenkov,

We have a broken Netapp filer and no plan to fix it. So we keep broken filer disk drver as spare for FAS250 filer. Due to the broken Netapp filer was long time can not power on. We don't know what exactly version of DataONTAP. Does it matter for FAS250 filer? Do we need to wipe the disk driver before we add to FAS250 filer?

We have try to add back to FAS250 filer, Using "storage show disk -x". it show:

DISK SHELF BAY SERIAL VENDOR MODEL REV

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

0b.16 1 0 DH07P870CVJL NETAPP X276_FAL9E288F10 NA04

0b.22 1 6 DH07P870CWHC NETAPP X276_FAL9E288F10 NA05

As you can see, we put the used disk driver on Bay0, But the disk driver firmware version is "NA04". It seems like older than on-line disk driver.

Another problem is, when we run "aggr status" command, it show below messages:

nas> aggr status

Aggr State Status Options

aggr0 online raid_dp, aggr root

degraded

aggr0(1) failed raid_dp, aggr diskroot, raidsize=28,

foreign lost_write_protect=off

partial

Very strange, it create aggr0(1) automatically. What happen to it? Is it normal?

aborzenkov — Thu, 25 Jul 2013 04:16:14 GMT

Your replacement disk was part of aggregate aggr0. Now filer imported this aggregate, renamed it to avoid confusion. It is failed because other disks from this aggregate are obviously missing. You need to destroy this foreign aggregate to make new disk spare.

martin_fisher — Thu, 25 Jul 2013 08:53:30 GMT

Yeap - as i thought. The disk inserted has old metadata, regarding the old Filer. When you inserted the disk, ONTAP has detected this, shown by aggr status, as aborzenkov stated. the foreign aggr needs destroying and the disk inserted in bay0 as a spare disk, zero'ing.

once this is completed your correct aggr 1 should rebuild.

YHCHEN168 — Thu, 25 Jul 2013 13:59:57 GMT

Dear aborzenkov, Martin,

Thanks for your help!

We will try to destorying the foreign aggr and zeroing the disk driver ASAP.

Once more thing, We noticed the Bay0 disk driver firmware version is NA04. It looks like older than other disk drives. Does it matter? We have access "/etc/disk_fw" directory and can not found NA05 firmware. Do we need to upgrade the replacement disk to NA05 version for compatible reason? If so, where can i download disk driver firmware? I have searched Netapp web site, but can not found it. Maybe we do have rights to download it?

Dear all,

We have followed your suggestions and the filer starting to rebuild the replaced disk. It fininsed with successed. Now everything looks fine, except the replacement disk dirver firmware is older than others. We will keep looking for disk firmware for further update. Thanks all. It's very appreciated for your help!

Hi - you should be able to see the Disk Firmwares currently available on your system, by setting the CLI to advanced and running the following command:

ls /etc/disk_fw

The disk firmware's available on your system are kept in this folder.

You should be able to manually update the disk firmware on the affected disk, using the command:

disk_fw_update

If you run a sysconfig -v this will show you the current disk FW and the disk ID.

Updating the disk Firmware is disruptive, so ideally you want to do this at a quiet period.
