7-5 Expanding an Integrated Mirroring Volume with
OCE
You can use the online capacity expansion (OCE) feature to expand the capacity of a
two-disk Integrated Mirroring (RAID1) volume by replacing the original disks with two
larger disk drives while the volume remains online. This process maintains data integrity
at all times, even if one of the disks fails during the replacement process. The new disks
must be at least 50 GB larger than the disks they are replacing, and they must use the
same protocol (SAS or SATA) as the disks they are replacing.
Follow these steps to expand an existing RAID1 volume with OCE:
1. Physically replace one of the two volume disk drives with a drive that is at least 50
GB larger.
If necessary, you can identify the disks in the volume by following the instructions in
Locating Disk Drives in a Volume.
2. Wait until synchronization is complete on the new disk and the volume returns to the
optimal state, as indicated in the A
DAPTER

ROPERTIES
screen (see Figure 7-2 ) of
the SAS2 BIOS Configuration Utility.
3. Physically replace the other volume disk drive with a drive that is at least 50 GB
larger.
4. Again, wait until synchronization is complete on the new disk and the volume
returns to the optimal state.
5. In the A
