Note: The path ID can be specified at Continuous Access Synchronous. The path ID can also be
specified at Cnt Ac-J/Cnt Ac-J Z when connecting P9500s. The same path ID must be specified
between the site of P-VOL and S-VOL because the path ID is used at the paircreate command.
(8) HORCM_ALLOW_INST
The HORCM_ALLOW_INST parameter is used to restrict the users using the virtual command
device. Allowing IP address and port numbers are as follows.
For IPv4
HORCM_ALLOW_INST
#ip_address service
158.214.135.113 34000
158.214.135.114 34000
For IPv6
HORCM_ALLOW_INST
#ip_address service
fe80::209:6bff:febe:3c17 34000
Note: If RAID Manager clients not defined HORCM_ALLOW_INST, HORCM instance starting up
is rejected by SCSI check condition (SKEY=0x05, ASX=0xfe) and RAID Manager cannot be started
up.
Configuration definition for cascading volume pairs
The RAID Manager software (HORCM) is capable of keeping track of up to seven pair associations
per LDEV (1 for Continuous Access Synchronous/Cnt Ac-J, 3 for Cnt Ac-J, 3 for Business
Copy/Snapshot, 1 for Snapshot). By this management, RAID Manager can be assigned to seven
groups per actual LU that is described to the configuration definition file.
Figure 15 Mirror descriptors and group assignment
Configuration file and mirror descriptors
The group name and MU# described in the HORCM_DEV parameter of a configuration definition
file are assigned the corresponding mirror descriptors, as outlined in
. "Omission
of MU#" is handled as MU#0, and the specified group is registered to MU#0 on Business Copy
and Continuous Access Synchronous. Also, the MU# that is noted for HORCM_DEV in
reflects a random numbering sequence (for example, 2, 1, 0).
