C–8 Cluster Troubleshooting
To check system parameter values on a satellite node that cannot boot, invoke the
SYSGEN utility on a running system in the OpenVMS Cluster that has access to the
satellite node’s local root. (Note that you must invoke the SYSGEN utility from a node
that is running the same type of operating system—for example, to troubleshoot an Alpha
satellite node, you must run the SYSGEN utility on an Alpha system.) Check system
parameters as follows:
Step Action
A Find the local root of the satellite node on the system disk. The following
example is from an Alpha system running DECnet for OpenVMS:
$ MCR NCP SHOW NODE HOME CHARACTERISTICS
Node Volatile Characteristics as of 10-JAN-1994 09:32:56
Remote node = 63.333 (HOME)
Hardware address = 08-00-2B-30-96-86
Load file = APB.EXE
Load Assist Agent = SYS$SHARE:NISCS_LAA.EXE
Load Assist Parameter = ALPHA$SYSD:[SYS17.]
The local root in this example is ALPHA$SYSD:[SYS17.].
Reference: Refer to the DECnet–Plus documentation for equivalent information
using NCL commands.
B Enter the SHOW LOGICAL command at the system prompt to translate the
logical name for ALPHA$SYSD.
$ SHO LOG ALPHA$SYSD
"ALPHA$SYSD" = "$69$DUA121:" (LNM$SYSTEM_TABLE)
C Invoke the SYSGEN utility on the system from which you can access the
satellite’s local disk. (This example invokes the SYSGEN utility on an
Alpha system using the Alpha parameter file ALPHAVMSSYS.PAR. The
SYSGEN utility on VAX systems differs in that it uses the VAX parameter file
VAXVMSSYS.PAR). The following example illustrates how to enter the SYSGEN
command USE with the system parameter file on the local root for the satellite
node and then enter the SHOW command to query the parameters in question.
