InForm OS Version 2.3.1 Command Line Interface Reference
The following example shows how to use the tunetpvv command to increase the availability
level of a TPVV (
testvol). Note that there is mag availability because testvol was originally
on
cpg1, which is created with option (–ha mag). To increase cage availability, create a CPG
with cage availability and tune
testvol to the associated CPG.
The following example shows how to tune multiple VVs together.
Testvol.0, testvol.1
and
testvol.2 are the three VVs to be tuned:
NOTES
■ When canceling a tunetpvv command task, the canceltask command may return
before a cancellation is complete. Thus, resources reserved for the task may not be
immediately available. This will prevents actions like attempting another tune on the same
VV. Scripts should use the
waittask command in order to ensure orderly completion of
the
tunetpvv command cancellation prior to taking other actions.
