6.2.2.3 Assigning Node Allocation Class Values on HSJ Subsystems
To assign a node allocation class value for disks for an HSJ subsystem, enter a
SET CONTROLLER MSCP_ALLOCATION_CLASS command in the following
format:
SET CONTROLLER MSCP_ALLOCATION_CLASS = allocation-class-value
To assign a node allocation class value for tapes, enter a SET CONTROLLER
TMSCP_ALLOCATION_CLASS ALLOCATE TAPE command in the following
format:
SET CONTROLLER TMSCP_ALLOCATION_CLASS = allocation-class-value
For example, to assign or change the node allocation class value for disks to 254
on an HSJ subsystem, use the following command at the HSJ console prompt
(PTMAN>):
PTMAN> SET CONTROLLER MSCP_ALLOCATION_CLASS = 254
6.2.2.4 Assigning Node Allocation Class Values on HSD Subsystems
To assign or change allocation class values on any HSD subsystem, use the
following commands:
$ MC SYSMAN IO CONNECT FYA0:/NOADAP/DRIVER=SYS$FYDRIVER
$ SET HOST/DUP/SERVER=MSCP$DUP/TASK=DIRECT node-name
$ SET HOST/DUP/SERVER=MSCP$DUP/TASK=PARAMS node-name
PARAMS> SET FORCEUNI 0
PARAMS> SET ALLCLASS 143
PARAMS> SET UNITNUM 900
PARAMS> WRITE
Changes require controller initialization, ok? [Y/(N)] Y
PARAMS> EXIT

6.2.2.5 Assigning Node Allocation Class Values on DSSI ISEs
To assign or change node allocation class values on any DSSI ISE, the command
you use differs depending on the operating system.
For example, to change the allocation class value to 1 for a DSSI ISE TRACER,
follow the steps in Table 6–2.
6–10 Cluster Storage Devices
Table 6–2 Changing a DSSI Allocation Class Value
Step Task
1 Log into the SYSTEM account on the computer connected to the hardware device TRACER
and load its driver as follows:
• If the computer is an Alpha system, then enter the following command at the DCL
prompt:
$ MC SYSMAN IO CONN FYA0:/NOADAP/DRIVER=SYS$FYDRIVER
• If the computer is a VAX system, then enter the following command at the DCL
prompt:
$ MCR SYSGEN CONN FYA0:/NOADAP/DRIVER=FYDRIVER
