Requirement
8 paths at maximum, from MCU to RCU.
Fibre Channel, direct or with switch connections. See
Maximum of eight from primary system to secondary system.
Logical paths are established for primary and secondary systems CUs separately.
Maximum number of logical paths allowed for a primary system is 32 (8 paths per
secondary system x 4 secondary systems per primary system).
Maximum of four secondary system per primary system.
Each secondary system CU must be added separately to a primary system.
P-VOL and S-VOL must be equal in size.
The maximum size of P-VOL and S-VOL is 4,194,304.000MB(8,589,934,592 blocks).
However, when primary system or secondary system is XP12000 Disk Array/XP10000
Disk Array, it is 2,949,120.00MB(6,039,797,760 blocks).
The minimum size of P-VOL and S-VOL is 48.000MB(96,000 blocks) for OPEN-V. It
is 36.000MB(72,000 blocks), except for OPEN-V.
One P-VOL may only be copied to one S-VOL.
P-VOL and S-VOL can be shared with other program product volumes. See
types that can be shared with Continuous Access Synchronous" (page
See "Planning volume pairs" (page 17)
Limited per P9500 system. See
Required for disaster recovery.
Recommended for data migration.
See "Host failover software" (page 27)
Remote Web Console
◦ Required
◦ Storage Administrator (Remote Copy) role is required. The primary system must be
LAN-attached to a Remote Web Console computer.
◦ The secondary system should be attached using a separate LAN at the remote site.
RAID Manager
◦ Optional
◦ Command device required for each RAID Manager instance. See the HP
StorageWorks P9000 RAID Manager User Guide for information on setting up and
using RAID Manager.
