The master volume should say LONER-RO, which means that it is closed and access is
defined as Read-Only. MPE/iX will not let you mount a Read-Only disk because it is not
supported on MPE/iX. The Read-Only attribute is set by the XP256 while it is active
copy mode.
Business Copy Procedures
On System A
VSCLOSE PRODUCTION_DATA;NOW
This will quiesce I/Os to the volume set and flush all files and data
structures resident to that volume set to disk.
Within the Remote Control PC make sure that the primary and Business
Copy disks are in sync and then split the primary volumes from the
Business Copy volumes.
(After the split you may VSOPEN the PRODUCTION_DATA volume set on
System A and continue operations)
On System B
After the primary volumes have been split from the Business Copy you can issue the
VSOPEN PRODUCTION_DATA command on System B and start operations.
When operations are completed, VSCLOSE PRODUCTION_DATA;NOW and from the Remote
Control PC re-establish the primary and Business Copy mode. There is no need to log off
users from System A to re-establish Business Copy.
