Managing your system and non-system disks provides several key benefits. Disk
management can reduce downtown caused by system installation,
system failure, or disk failure. With proper disk management,
if you need to install a new system, you need to reload only the system
volume set. Similarly, if the system fails for any reason, you may move
removable disk packs to another system where processing can continue.
Disk management also provides greater data availability
(via data partitioning) and more efficient use of limited resources.
And finally, disk management can improve data security.
If you use removable disk packs, you can take sensitive data offline and place
it in a secure location. Or, you can
use special capabilities to protect data on nonsystem volumes.
In this chapter, you can find the following topics:
managing master and member volumes
creating a nonsystem volume set
creating the account structure
managing permanent and transient storage
determining free disk space
