Environment
Novell Open Enterprise Server 2 (OES 2) Linux SP2
Situation
CIFS not enabled properly on cluster resource that was created before upgrading to OES2 SP2
CIFS object class and attributes are not added to the virtual server object
cifsPool.py script fails with -610 error
Resolution
When a resource is created prior to SP2, the CIFS attributes are not added to the virtual server object even if CIFS is checked. When CIFS is checked on an existing resource using iManager (prior to sp2), the novcifs command is added to the scripts with an incorrect format. The cifsPool.py script is needed to correct the novcifs format and to add the attributes to the virtual server object.
When a resource is created in SP2, the CIFS attributes are added to the virtual server object even if CIFS is not checked. When CIFS is checked on an existing resource using iManager on SP2, the novcifs command is added to the scripts with the correct format. The cifsPool.py script is not needed.
If a resource is created prior to SP2 and then iManager on SP2 is used to check CIFS, the attributes are not added to the virtual server object, but the novcifs command has the correct syntax. The cifspool.py script fails because the load script has the correct syntax for novcifs.
See Additional Information for a modified version of cifsPool.py that will work when the novcifs command in the load script has the correct syntax. Copy the content of Additional Information to a file and use the same syntax as cifsPool.py. cifsPool.py syntax
Additional Information
Script to add CIFS object class and attributes to virtual server object when the novcifs command in the load script has the correct syntax
