To determine the port number for dummy LUs, use the following formula:
Port#:Installed Port#(*1) (LDEV# / 0x4000) × 32
Installed Port#(*1) (LDEV# / 0x4000) × 32+1
*1: The lowest port number of the installed mainframe ports.
TID: (LDEV# & 03xFCO)/64
LU-M: (LDEV# &0x3F)
To perform pair operations on mainframe volumes just like on open-system
volumes, include the mainframe LDEV# in the HORCM_LDEV section of the
configuration definition file. If you have mainframe pairs that already exist,
you can verify their MU # using the raidscan command.
Pair status and access permission for mainframe LDEVs
The pair status of mainframe LDEVs is displayed in the same way as for
open-system LDEVs. However, access permissions to mainframe P-VOLs and
S-VOLs are different from those of open volumes. The following tables show
the pair status and access permissions for mainframe LDEVs. For more
information about displayed pair status of open LDEVs, see
TrueCopy/
ShadowImage/Universal Replicator pair status on page 6-18.
