When you add partitioned disks to an aggregate, you must leave a disk with both the root and data partition available as spare for every node. If you do not and your node experiences a disruption, ONTAP cannot dump the core to the spare data partition.
You display your spare partitions for node c1-01 and see that your spare partitions are not aligned:
c1::> storage aggregate show-spare-disks -original-owner c1-01 Original Owner: c1-01 Pool0 Shared HDD Spares Local Local Data Root Physical Disk Type RPM Checksum Usable Usable Size --------------------------- ----- ------ -------------- -------- -------- -------- 1.0.1 BSAS 7200 block 753.8GB 0B 828.0GB 1.0.10 BSAS 7200 block 0B 73.89GB 828.0GB
You start the disk replacement job:
c1::> storage disk replace -disk 1.0.1 -replacement 1.0.10 -action start
While you are waiting for the replacement operation to finish, you display the progress of the operation:
c1::> storage aggregate show-status -aggregate aggr0_1 Owner Node: c1-01 Aggregate: aggr0_1 (online, raid_dp) (block checksums) Plex: /aggr0_1/plex0 (online, normal, active, pool0) RAID Group /aggr0_1/plex0/rg0 (normal, block checksums) Usable Physical Position Disk Pool Type RPM Size Size Status -------- --------------------------- ---- ----- ------ -------- -------- ---------- shared 1.0.1 0 BSAS 7200 73.89GB 828.0GB (replacing, copy in progress) shared 1.0.10 0 BSAS 7200 73.89GB 828.0GB (copy 63% completed) shared 1.0.0 0 BSAS 7200 73.89GB 828.0GB (normal) shared 1.0.11 0 BSAS 7200 73.89GB 828.0GB (normal) shared 1.0.6 0 BSAS 7200 73.89GB 828.0GB (normal) shared 1.0.5 0 BSAS 7200 73.89GB 828.0GB (normal)
After the replacement operation is complete, you confirm that you have a full spare disk:
