9. In the Pairresync dialog box, use the following settings: • For P-VOL Fence Level, specify Never. • In Change attribute to ESAM, specify Yes. • In Quorum Disk ID, specify a quorum disk ID for the ESAM pair. 10.

pairs:
•
Though the host recognizes the ESAM volumes as a single volume, RAID Manager views the
P-VOL and S-VOL as separate volumes.
•
RAID Manager shows the ESAM pair, the Continuous Access Synchronous pair, and the UR
pair, according to the following table.
