Checking Result Of Clpr Transfer - Hitachi VSP F1500 User And Reference Manual

distributed parity group have to be allocated the same CLPR. Parity groups
including LDEVs where cache area of Cache Residency is defined cannot be
moved to another CLPR. For the restrictions on the CLPR's transfer, see the
Performance Guide . The following shows examples of parity groups transfer
in CLPR.
Move the parity group 32-17 to the CLPR number 1.
# raidcom modify clpr -clpr 1 -parity_grp_id 32-17
When you move parity groups by specifying their LDEV numbers, use LDEV
numbers for virtual volumes of Dynamic Provisioning, Copy-on-Write
Snapshot, or Thin Image. When you move other volumes, specify a parity
group number or external volume group number. The following shows an
example of moving a virtual volume of Dynamic Provisioning, Copy-on-Write
Snapshot, or Thin Image.
Move the virtual volume of LDEV number: 02:00 to CLPR ID: 2.
# raidcom modify clpr -clpr 2 -ldev_id 0x0200

Server Priority Manager operations
Server Priority Manager enables you to prioritize host I/O operations to
provide high-speed processing for specified hosts. The host is identified by
the WWN or iSCSI name of the host bus adapter. Server Priority Manager has
two settings: prioritized and non-prioritized. Set the prioritized option for
hosts that require high-speed processing, and the non-prioritized option for
the other hosts.
The following methods are used to set the priority level, but only one of them
can be used in a single storage system:
• Specifying ports and WWNs of host bus adapters
