Syntax
arcconf modify controller_id array array_id expand channel_id slot_id
channel_id slot_id
......
Parameters
controller_id: Specifies the ID of the storage controller.
array_id: Specifies the ID of an array.
channel_id: Specifies the channel ID of a drive.
slot_id: Specifies the device ID of a drive.
Description
Adding new drives to RAID 1/1ADM/10 might cause the RAID level to increase depending on
the number of the added drives.
During expansion by adding drives, you can add only one drive for RAID 0/RAID 5/RAID 6 at a
time, two drives for RAID 50/RAID 60 at a time, and three drives for RAID10ADM at a time.
After adding a drive, see "Scale up a logical drive" to scale up logical drives.
Examples
# Add new drives to the array.
[root@localhost ~]# arcconf modify 1 array 0 expand 0 10
Controllers found: 1
This will modify the array 0.
Are you sure you want to continue?
Press y, then ENTER to continue or press ENTER to abort: y

Command completed successfully.
Migrate the RAID level
Perform this task to migrate the RAID level.
Syntax
arcconf modify controller_id from LD_id to LD_size LD_level channel_id
slot_id channel_id slot_id
......
Parameters
controller_id: Specifies the ID of the storage controller.
LD_id: Specifies the ID of a LD.
LD_size: Specifies the capacity of the LD before migration.
LD_level: Specifies the LD level after migration.
channel_id: Specifies the channel ID of a drive.
slot_id: Specifies the device ID of a drive.
Usage guidelines
If the number of drives required for the target level of migration is more than the original level,
you must first add drives to the LD and then perform migration. Adding new drives to RAID
