Displaying Profile Attributes
OSSCaching
shows whether caching for Open System Services (OSS)
files is enabled.
PhysvolSelect
(magnetic disks only) shows whether a virtual disk process
is allowed to consider the physical volume for file placement.
Pool
the storage pool process with which the disk volume is
associated.
Program
shows the object file name of the disk process.
ProtectDirectory
the type of protection to use for the disk volume directory:
full-block checking (CHECKPOINT), serial writes (SERIAL),
or disabled (OFF).
ReviveBlocks
the number of revive blocks of disk data to be copied during
each copy interval when the disk is being revived.
ReviveInterval
the interval of time, in 10-millisecond units, between each
copy operation and the next when the disk is being revived
SerialWrites
(mirrored volumes only) specifies whether serial writes are
used when updating files. ENABLED minimizes the
potential data loss caused by certain processor error
conditions. DISABLED maximizes the performance of
mirrored volumes.
When ENABLED, the IOP performs serial write operations
when the mirror disk is up. If the mirror disk is not up and if
the FullCheckpoints value is FORCED or ENABLED,
full-block checkpoints are used to protect the validity of the
data. See also the FULLCHECKPOINTS attribute on page
14-57.
StartState shows whether the disk process is enabled (STARTED)
or disabled (STOPPED) when the disk process is
launched.
