Setting Up Integrated Mirroring 21
The IM volume exists as soon as you save the changes, and the Mirroring Properties screen displays
the IM volume properties and status.
Other Mirroring Properties Screen Information
After the IM volume is created, the Volume SCSI ID field shows which SCSI ID the operating
system uses to access the IM volume (figure 3-5). This addressing information stays the same
unless you reconfigure the volume with disks that have different SCSI IDs. The IM volume
addressing information will also change if the SCSI ID is changed for the physical disk whose SCSI
ID is being used for the IM volume.
The Size field shows the capacity of the IM volume. The volume size is slightly less than half of the
combined capacity of the mirrored disks, because the utility rounds the size down to increase
compatibility in case a disk of the volume must be replaced. (Even if replacement disks are of the
same size class, they may differ slightly in actual capacity.)
The screen in figure 3-5 shows the properties and status of each disk in the IM volume. The Status
column may show any of these values:
OK , disk missing , incompatible , offline , out of sync , or disk
initializing
.
