Verifying An Array; C.2.4 Verifying An Array - Impediment RS-1600-X24 User Manual

The LUN screen displays.
7 Select the LUN for the partition and press Enter.
The LUN that displays is the suggested default LUN assignment.
Note Most UNIX, Linux, and Macintosh operating systems require that the CAPI LUN, which is the LUN
assigned to each SM, be set to a higher value than all array LUNs. Before creating your first array, change
the CAPI LUN to a higher value. If you are using a custom software application to configure and manage
the X24 subsystem (this application uses CAPI to communicate with the X24), you must have a CAPI
LUN. If you are not using a custom application, and therefore are not using CAPI, select NONE as the
CAPI LUN. This allows your first array to be seen at LUN 0.
The system warns you about the LUN for UNIX and Macintosh, as above, the first time you create a
partition. Press Enter and the system asks if you want to be warned again. Select No to avoid receiving
this warning again, otherwise select Yes to be warned the next time you create a partition.
The system confirms that you want to make the change.
8 Select Yes and press Enter.

C.2.4 Verifying an Array

The Verify function allows you to verify the data on the specified array (RAID 3, RAID 4, RAID 5, RAID
50, and mirrored arrays only):
• RAID 3, RAID 4, RAID 5 and RAID 50: Verifies all parity blocks in the selected array and corrects
any bad parity.
• Mirrored: Compares the primary and secondary drives. If a mismatch occurs, the primary is copied
to the secondary.
