ALTER POOL Command
AUDITED { ALLOWED | DISALLOWED | REQUIRED }
is the type of volume you can add to the storage pool.
BACKUPCPU number
is the processor in which the backup IOP starts. The process must be in the
STOPPED state or not running for you to alter this attribute.
DISKINTERVAL number
is the interval (as a percentage) that, with the DISKTHRESHOLD attribute, is used
by the disk process to determine when to issue a disk-full EMS message for
physical volumes in the storage pool. For example, if DISKTHRESHOLD is 70 and
DISKINTERVAL is 5, the disk process issues an EMS message when the disk
becomes 70, 75, 80, 85, 90, and 95 percent full.
number is either -1 (the default, no disk-full EMS messages are issued) or in the
range 1 through 99 percent.
This attribute has no effect if DISKTHRESHOLD is -1.
DISKTHRESHOLD number
is the threshold (as a percentage) that, with the DISKINTERVAL attribute, is used
by the disk process to determine when to issue a disk-full EMS message for
physical volumes in the storage pool. For example, if DISKTHRESHOLD is 75, the
disk process generates an EMS message when the physical volume becomes 75
percent full. If you also specify DISKINTERVAL, the disk process generates an
EMS message when the physical volume becomes 75, 80, 85, 90, and 95 percent
full.
number is either -1 (the default, no disk-full EMS messages are issued) or in the
range 1 through 100 percent.
EXTENTINTERVAL number
is the number of extents that, with the EXTENTTHRESHOLD attribute, is used by
the disk process to determine when to issue an extents-left EMS message for
physical volumes in the storage pool. For example, if EXTENTTHRESHOLD is 6
and EXTENTINTERVAL is 2, the disk process issues an EMS message when
there are 6, 4, 2, and 0 extents left to be allocated for a file.
number is either -1 (the default, no extents-left EMS messages are issued) or in
the range 1 through 978.
This attribute has no effect if EXTENTTHRESHOLD is -1.
ALLOWED You can add any volume, even if it is not protected by TMF
(default).
DISALLOWED You can add a volume only if it is not protected by TMF.
REQUIRED You can add a volume only if it is protected by TMF.
