Figure E-2: Array capacity expansion
The unused capacity on the enlarged array can now be used to create an additional
logical drive, with a different fault-tolerance setting if necessary.
Alternatively, the unused capacity can be used to increase the size of one of the
original logical drives; this process is logical drive capacity extension. Another
method for carrying out logical drive capacity extension is to delete an existing
logical drive and then to add the freed capacity to another logical drive.
Capacity expansion is carried out using one of the utilities described in Chapter 6,
“Configuring an Array”. For reconfiguration to occur online (that is, without shutting
down the operating system), the configuration utility must be running in the same
environment as the normal server applications. Also, online expansion is possible
only in systems that are using hot-pluggable drives.
Only ACU and ACU 6.0 support capacity extension. Also, not all operating systems
allow extension to be carried out while the system is online. For details, refer to
Chapter 6, “Configuring an Array.”
