ALTER DISK Command
AUDITTRAILBUFFER number
(TMF audit-trail volumes only) is the audit-trail buffer size (in megabytes) for an
audit volume. This value improves the performance of systems that use the
Remote Duplicate Database Facility. number is in the range 0 (no buffer specified)
through 768. The default is 0. Do not use this attribute for SQL/MX volumes.
If you specify too large or small a value, DP2 automatically sets the needed size.
If you specify a value of 0, DP2 automatically sets the size of the DP2 audit-trail
volume log cache, which defaults to 1 MB, that is, 256 audit-trail buffers.
AUTOREVIVE { ON | OFF }
(mirrored disks only) specifies whether to automatically start a revive operation on
a mirrored volume either when either a new disk is inserted or when the system is
loaded and a mirrored volume is not synchronized.
For information about using this attribute, see Configuring Internal Mirrored
Magnetic Disks to Revive Automatically on page 6-13.
AUTOSELECT { ON | OFF }
specifies whether a virtual disk process is allowed to automatically consider this
physical volume when making file-placement decisions. This attribute is valid only
when this physical volume is a member of a storage pool.
AUTOSTART { ON | OFF }
(internal and M8xxx disks only) specifies whether to automatically start the disk
process when the disk is inserted.
DISK AUTOSTART ON is ignored if SUBSYS AUTOSTART is OFF.
For information about using this attribute, see Mirrored Disk Placement on
page 6-12.
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.
ON Automatically starts a revive operation using the values for the
REVIVEPRIORITY and REVIVERATE attributes.
OFF Does not automatically start a revive operation (default).
ON Enable automatic selection (default).
OFF Disable automatic selection.
ON Enable automatic starting (default).
