Cluster Troubleshooting
C.3 Satellite Fails to Boot
C.3.4 Disk Server Troubleshooting
To diagnose and correct problems for disk servers, follow the steps outlined in
this section.
Step Action
1 Perform the steps in Section C.3.2.
2 For each satellite node, verify the following system parameter values:
MSCP_LOAD = 1
MSCP_SERVE_ALL = 1
3 The disk servers for the system disk must be connected directly to the disk.
C.3.5 Satellite Booting Troubleshooting
To diagnose and correct problems for satellite booting, follow the steps outlined in
this section.
Step Action
1 Perform the steps in Sections C.3.2, C.3.3, and C.3.4.
2 For each satellite node, verify that the VOTES system parameter is set to 0.
3 ‡On Alpha systems, verify the DECnet network database on the MOP servers by running
the NCP utility and entering the following commands to display node characteristics. The
following example displays information about an Alpha node named UTAH:
$ MCR NCP
NCP> SHOW NODE UTAH CHARACTERISTICS
Node Volatile Characteristics as of 15-JAN-1994 10:28:09
Remote node = 63.227 (UTAH)
Hardware address = 08-00-2B-2C-CE-E3
Load file = APB.EXE
Load Assist Agent = SYS$SHARE:NISCS_LAA.EXE
Load Assist Parameter = $69$DUA100:[SYS17.]
The load file must be APB.EXE. In addition, when booting Alpha nodes, for each LAN
adapter specified on the boot command line, the load assist parameter must point to the
same system disk and root number.
4 †On VAX systems, verify the DECnet network database on the MOP servers by running
the NCP utility and entering the following commands to display node characteristics. The
following example displays information about a VAX node named ARIEL:
†VAX specific
‡Alpha specific
C–10 Cluster Troubleshooting
$ MCR NCP
NCP> SHOW CHAR NODE ARIEL
Node Volatile Characteristics as of 15-JAN-1994 13:15:28
Remote node = 2.41 (ARIEL)
Hardware address = 08-00-2B-03-27-95
Tertiary loader = SYS$SYSTEM:TERTIARY_VMB.EXE
Load Assist Agent = SYS$SHARE:NISCS_LAA.EXE
Load Assist Parameter = DISK$VAXVMSRL5:
Note that on VAX nodes, the tertiary loader is SYS$SYSTEM:TERTIARY_VMB.EXE.
