Creating an Alternate System
Volume and Adding and Deleting
Logical Targets
This section describes adding and deleting logical targets from a DSM/SCM host or
target system, and adding an alternate $SYSTEM:
Considerations
Before adding additional logical targets, remember that:
•
You cannot maintain more than six logical targets on a single system.
•
Each logical target requires its own $SYSTEM and a unique alternate volume. The
primary volume name for each logical target must be $SYSTEM, and the alternate
volume name for each of these targets must be different to differentiate between
the disks.
•
Each time you switch from one logical target to another, you must perform a
system load.
•
You cannot perform an initialization Build/Apply if it has been previously performed
on any other logical target created on that particular physical target system.
Creating an Alternate System Volume
1. Change the primary volume name to $SYSTEM. See these manuals:
