Troubleshooting Problems With Adding a Virtual
Disk
Troubleshooting Problems With Adding a Virtual Disk
1. Use an INFO or STATUS command to detect problems when adding a virtual disk:
•
The INFO command displays a process that has a configuration record but the
Configuration State is “No Definition With SMF master process.”
•
The STATUS command also displays the Configuration State “No Definition
With SMF master process.”
2. Check the EMS event messages for the storage subsystem.
The ADD DISK Command Fails
An ADD DISK command can fail if a record for the given name exists or if the SMF
Master Process already has a definition for a virtual disk of the given name.
For example, if SCF successfully adds the configuration record but then cannot define
the process by using the SMF Master Process, SCF attempts to delete the
configuration records. If this action fails, SCF puts out a message to warn that
configuration records remain although there is no definition in the SMF Master
Process.
This inconsistency can also occur if a processor failure happens after the configuration
records are added but before the defining with the SMF Master Process is done.
To recover, delete the incorrect entry. See Deleting a Virtual Disk on page 10-11. If the
DELETE command fails, alter the STARTSTATE attribute to STOPPED to ensure that
the process does not unexpectedly start.
Storage Subsystem Message 9026
If you get storage subsystem message 9026 while adding a storage pool process or
virtual disk, the error is caused by an inconsistency between SMF and the system
configuration database (the storage pool or virtual disk is defined in SMF but is not
defined in the system configuration database). In this case, you can:
•
Add the storage pool or virtual disk without using the SMF attributes.
•
Add the storage pool or virtual disk using the same attributes that are defined in
SMF.
