ADD DISK Command
If the RESET or START command fails, you must reload the backup processor. 
HIGHPIN { ON | OFF } 
specifies whether the IOP can run at a high PIN (ON, the default) or only at a low 
PIN (OFF). 
LKIDLONGPOOLLEN number 
is the amount of memory (in 128-kilobyte units) to be allocated for lock key space. 
This space stores keys larger than 16 bytes when records in key-sequenced files 
are locked. number  is in the range 0 through 512. A value of 0 causes DP2 to 
use an internal default value. For the ADD command, the default value is 8.
LKTABLESPACELEN number 
is the memory (in 128-kilobyte units) to be allocated for lock-related data 
structures. The memory available for these structures limits the total file and record 
locks allowed on the disk. number is in the range 0 through 512. A value of 0 
causes DP2 to use an internal default value. For the ADD command, the default 
value is 15. 
MAXLOCKSPEROCB number 
is the maximum records that can be locked outside a transaction. number  is in 
the range 5000 through 100000. The default is 5000.
MAXLOCKSPERTCB number 
is the maximum number of records and files that a transaction can lock. number  
is in the range 5000 through 100000. The default is 5000.
MBACKUPDEVICEID {{ number | ( shelf, bay ) } 
(45xx and M8xxx Fibre Channel disks only) is the device ID of the disk accessed 
on the mirror backup path to the disk. This attribute is optional. If specified, it must 
be the same device ID that you specified for the MIRRORDEVICEID (page 14-16
). 
For 45xx disks:
For M8xxx Fibre Channel disks: 
If you configure a disk volume for use with an FCSA connected to an ESS, you 
cannot specify MBACKUPDEVICEID.
number
is the unit number of the disk. number is in the range 1 
through 7.
shelf is the disk-drive enclosure’s shelf number. shelf  is in the 
range 1 through 4.
bay is the number of the disk. bay is in the range 1 through 14.
