NetApp FAS Health Check and Disk Replacement

Login Node

If logged in to SP mode, first execute: system console

If logged in to Cluster mode, first execute: system node run -node local

Health Check

1. Execute on both nodes separately

vol status -s check for hot spare disks

vol status -f check for failed hard drives

vol status -r check all hard drive statuses

environment status  Check power supply and fan status (or use storage show fault)

I. Hard Drive Replacement Maintenance Steps (Perform on the controller where the failed disk is located):

1. Log in to the controller to which the failed hard drive belongs

2. vol status -f view bad disks (disks under Broken disks); if a disk exists, the hot spare has already taken over

3. Remove the hard drive, wait 30 seconds, then insert the new hard drive (confirm the yellow light is on and the green light is not flashing)

4.disk show -v  Check whether the new disk has been assigned an owner (controller)

5. disk assign **.**.** assign the hard drive to the current owner (controller); if not assigned, proceed to the next step

6.disk show -v  Check whether the assigned owner is correct; it should be the current controller

7. vol status -r check hard drive status; if the new hard drive appears under spare disks without 'not zerod' displayed afterward, maintenance is complete.

8. If the hot spare disk displays 'Not zerod', execute command disk zero spares to initialize the hot spare disk

(If the hard drive is marked with Bad Label, perform Step 4)

(If the hard drive has already entered spare disks and is marked as 'not zerod' at the end, proceed to Section II)

II. Initialize Hot Spare Disks Marked as not zerod

disk zero spares initialize all spare disks that are not zero

III. Handle Newly Replaced Hard Drives with Status 'Bad Label'

1. priv set advanced enter advanced mode

2. disk unfail -s **.**.** remove the Bad label

3. priv set exit advanced mode

IV. Handle Hard Drives Assigned to Unknown Owner (Controller)

1. disk show -v  View the owner (controller) of the new disk

2. disk assign -f <disk_id> -s unowned force assignment

3. disk assign **.**.** assign the hard drive to the current owner (controller)

*. disk assign -f **.**.** -s 348921*** force-assign the hard drive to a specific owner (controller)
