FAS3020 Aggregate aggr0 (online, raid_dp, degraded) (block checksums)

Hi,

We have a FAS3020 filer with 6 shelves.

Filer status shows error massage "There are not enough spare disks. /aggr0/plex0/rg0: Please add spare disks supporting block checksums with size: Used 635555/1301618176 (MB/blks)"

I don’t know which HD to replace, sysconfig -A does not determine the failed HD.

sysconfig -A output below:

Re: FAS3020 Aggregate aggr0 (online, raid_dp, degraded) (block checksums)

Hi,

try vol status -f command to identify which HDD was failed and vol status -s to check whether do you have enough space disks or not.

if you physically cannot find the failed disk. used led_on <disk.name> command in order to used this you need to go to advanced mode.

Re: FAS3020 Aggregate aggr0 (online, raid_dp, degraded) (block checksums)

Hi yem,

Ye is correct.  With the vol status -f  command u can find out the failed disk with its type.

Netapp1 > vol status -f

Regards,

Hari.

Re: FAS3020 Aggregate aggr0 (online, raid_dp, degraded) (block checksums)

it did not work with me

find below:

Re: FAS3020 Aggregate aggr0 (online, raid_dp, degraded) (block checksums)

can you show me the aggr status -r aggr0 output. and disk show -v output please. and according to your vol status -s output you do not have the spare disks to replace the failed disk. because all you spare disk are different form failed disks.

Regards,

Ye
