About unavailable storage unit problems
NetBackup jobs sometimes fail because storage units are unavailable, due to the disk drives or tape drives that are down or have configuration errors. The NetBackup processes log messages to the NetBackup error log that may help pinpoint and resolve these types of issues.
In addition, the Job Details dialog box available from the Activity Monitor contains the messages that describe the following:
The resources that the job requests
The granted (allocated) resources.
If a job is queued awaiting resources, the Job Details dialog lists the resources for which the job waits. The three types of messages begin with the following headers:
requesting resource ... awaiting resource ... granted resource ...
