HaltOnError
(continued)
If a halt is never forced (value 1) for any internally detected
disk-process failures, then the disk process takes the following
actions:
•
The primary disk process attempts to give ownership
of the disk to the backup disk process. If successful,
the primary disk process becomes the backup and
becomes “soft down.” If unsuccessful, the primary
disk process goes into the STOPPED state, substate
DOWN.
•
If the backup disk process is the process that
detected the failure, then the disk state remains
unchanged and the backup disk process becomes
“soft down,” but the process does not halt.
The primary disk process continues to function
without an active backup. To restore backup
operation, you must either reload the backup
processor or issue an SCF RESET DISK command to
restart the disk process. For example issue an SCF
command similar to:
-> RESET DISK $DATA00, FORCED
LKIDLongPoolLen shows the amount of memory (in 128-kilobyte units) to be
allocated for the lock key space. This space is used to store
keys larger than 16 bytes when locking records in
key-sequenced files.
LKTableSpaceLen shows the amount of memory (in 128-kilobyte units) to be
allocated for lock-related data structures. The amount of
memory available for these structures limits the total number
of file and record locks allowed on the disk.
MaxLocksPerOCB shows the maximum number of records that can be locked
outside a transaction.
MaxLocksPerTCB shows the maximum number of records and files a transaction
can lock.
NumDiskProcesses shows the number of disk processes allocated for the disk.
OSSCaching shows whether caching for Open System Services (OSS) files
is enabled (ON) or disabled (OFF).
PhysvolSelect shows whether the disk can be considered for file placement
by a virtual disk process.
Pool shows which pool process the disk volume is associated with.
