MetroCluster – Adding disks to an existing aggregate

 

Syntax:

1. Enter the following command:{ aggr | vol } add { aggrname | volname } ndisks[@disk-size]
aggrname is the name of the aggregate to which you are adding disks.
volname is the name of the traditional volume to which you are adding disks.
ndisks is the number of disks to use. Adding new disks will fail if the number of disks is an odd number.
disk-size specifies the disk capacity, in gigabytes. Half these disks must be in each disk pool.

Note:

1. While adding disks to a mirrored aggregate the disks will be split between the mirrored aggregates. Example: If 22 disks are specified to be added, 11 disks will be  added to each aggregate.
2. If you use the disk-size option, first determine the size of spare disks in the disk pools using the aggr status -r or vol status -r command.

Ensure that there are enough spares available before adding disks to an existing aggregate

test1*> aggr add aggr1 22
Note: preparing to add 18 data disks and 4 parity disks.

Addition of 6 disks to the aggregate has completed.

Run the aggr status -r command to verify the disks that have been added to the mirrored agrregate. The disks will be added to both the aggregates.

Note: You can also choose to add disks selected by Data OnTap to a mirrored volume.
