Making external mainframe volumes usable
To use external volumes with the XP10000/XP12000, you must usually use External Storage XP to perform
external volume mapping, and then use Volume Management’s Format or Format All command to format
the volumes (see ” Formatting LDEVs ” on page 71). However, when you format external mainframe volumes
in this way, the formatting operation might take a lot of time.
If you use the following procedure, you can make external mainframe volumes usable more quickly.
CAUTION: Only storage administrators can perform the following operation. Storage partition
administrators cannot perform this operation.
1. Zero-format external mainframe volumes.
