6.2.2.1 Assigning Node Allocation Class Values on Computers
There are two ways to assign a node allocation class: by using CLUSTER_
CONFIG.COM or CLUSTER_CONFIG_LAN.COM, which is described in
Section 8.4, or by using AUTOGEN, as shown in the following table.
Step Action
1 Edit the root directory [SYSn.SYSEXE]MODPARAMS.DAT on each node that boots from
the system disk. The following example shows a MODPARAMS.DAT file. The entries are
hypothetical and should be regarded as examples, not as suggestions for specific parameter
settings.
!
! Site-specific AUTOGEN data file. In an OpenVMS Cluster
! where a common system disk is being used, this file
! should reside in SYS$SPECIFIC:[SYSEXE], not a common
! system directory.
!
! Add modifications that you want to make to AUTOGEN’s
! hardware configuration data, system parameter
! calculations, and page, swap, and dump file sizes
! to the bottom of this file.
SCSNODE="NODE01"
SCSSYSTEMID=99999
NISCS_LOAD_PEA0=1
VAXCLUSTER=2
MSCP_LOAD=1
MSCP_SERVE_ALL=1
ALLOCLASS=1
TAPE_ALLOCLASS=1
2 Invoke AUTOGEN to set the system parameter values:
$ @SYS$UPDATE:AUTOGEN start-phase end-phase
3 Shut down and reboot the entire cluster in order for the new values to take effect.
6.2.2.2 Assigning Node Allocation Class Values on HSC Subsystems
Assign or change node allocation class values on HSC subsystems while the
cluster is shut down. To assign a node allocation class to disks for an HSC
subsystem, specify the value using the HSC console command in the following
format:
SET ALLOCATE DISK allocation-class-value
To assign a node allocation class for tapes, enter a SET ALLOCATE TAPE
command in the following format:
SET ALLOCATE TAPE tape-allocation-class-value
For example, to change the value of a node allocation class for disks to 1, set the
HSC internal door switch to the Enable position and enter a command sequence
like the following at the appropriate HSC consoles:
Ctrl/C
HSC> RUN SETSHO
SETSHO> SET ALLOCATE DISK 1
SETSHO> EXIT
SETSHO-Q Rebooting HSC; Y to continue, Ctrl/Y to abort:? Y
Restore the HSC internal door-switch setting.
Reference: For complete information about the HSC console commands, refer to
the HSC hardware documentation.
