[NETAPP] How to Add more disk to existing Aggregation ?

To use CLI to add disk to the existing aggregation, follow below steps:

1). First check the aggregation that need to be extended:

 

lab> aggr status aggr1 -v

Aggr State Status Options

aggr1 online raid_dp, aggr nosnap=off, raidtype=raid_dp,

raidsize=16,

ignore_inconsistent=off,

snapmirrored=off,

resyncsnaptime=60,

fs_size_fixed=off,

snapshot_autodelete=on,

lost_write_protect=on

Volumes: <none>

 

Plex /aggr1/plex0: online, normal, active

RAID group /aggr1/plex0/rg0: normal

 

lab> df -Am

Aggregate total used avail capacity

aggr0 256MB 244MB 12MB 95%

aggr0/.snapshot 13MB 10MB 2MB 79%

aggr1 128MB 0MB 128MB 0%

aggr1/.snapshot 6MB 0MB 6MB 0%

2). Check the available spares by run sysconfig -r, in this example,

lab> sysconfig -r

Aggregate aggr1 (online, raid_dp) (zoned checksums)

Plex /aggr1/plex0 (online, normal, active)

RAID group /aggr1/plex0/rg0 (normal)

spare v4.22 v4 1 6 FC:B - FCAL N/A 1020/2089984 1027/2104448

3) Next add 15 spare disk to the Aggr1,  because the max size of spindle for Raid Group(Raid-DP) is 16 so when 15 new spindles added,  a new Raid Group is created with additional 4 disks.

 

lab> aggr add aggr1 -d v4.29 v4.32 v4.33 v4.34 v4.35 v4.36 v4.37 v4.38 v4.39 v4.40 v4.41 v4.42 v4.43 v4.44 v4.45

Note: preparing to add 13 data disks and 2 parity disks.

Continue? ([y]es, [n]o, or [p]review RAID layout) p

The RAID group configuration will change as follows:

RAID Group Current NEW

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

/aggr1/plex0/rg0 5 disks 16 disks

/aggr1/plex0/rg1 4 disks

 

Continue? ([y]es, [n]o, or [p]review RAID layout) yes
