The quorum disk cannot be used by other software products, except as follows:
• Cache Partition can allocate the CLPR (virtually partitioned cache) to the quorum disk when
you map the quorum disk to the storage system.
• Performance Monitor can monitor usage or performance of the quorum disk.
The following sections clarify key information regarding the use of other software products.
Cache Partition
Virtually partition the cache (CLPR), and allocate the CLPR to the host that issues the I/O to the
ESAM pairs.
Cache Residency
With Cache Residency, you can improve data access performance by storing the ESAM data in
the storage system's cache memory.
Performance Monitor
• Performance Monitor is used to monitor usage or performance of the storage system. You can
also display statistical I/O data of ESAM and Continuous Access Synchronous pairs.
• When Performance Monitor data collection results in a large amount of data, significant traffic
on the P9500 internal LAN can occur. To prevent time-outs while performing ESAM operations
on the Remote Web Console computer, cancel Performance Monitor data collection activities.
LUN Manager
LU paths cannot be deleted after you create ESAM pairs. To delete the LU path, you need to release
the ESAM pair first.
Open Volume Management
• Customized Volume volumes can be assigned to ESAM pairs, provided that the S-VOL has
the same capacity as the P-VOL.
• To perform Customized Volume operations on an existing ESAM P-VOL or S-VOL, the pair
must be released first to return the volume to the SMPL status.
