This section provides a summary of new features provided in the current release of the product.
This section contains the following topics:
Dynamic Erase of Expired DASDtapes
Block ID Support in Catalog Records for SFS Directories
The DASDTAPE command provides CA VM:Backup administrators with the information they need to manage DASDtape storage, identify problems, and ensure that nightly jobs run smoothly.
Use the DASDTAPE command to:
Dynamic erase of expired DASDtapes provides a method for expired DASDtape TAPE files to be erased automatically, freeing up space for running backups.
These files are now erased when space is needed during a backup if the job writes to DASDtapes. The expired DASDtape TAPE files are only erased if the tape is not referenced in a catalog.
New Block ID fields in the CA VM:Backup catalog record allow backup tapes to be quickly positioned to the start of SFS directory data during restore processing.
These fields have been added to the CA VM:Backup DIRH catalog record and enable CA VM:Backup to rapidly position a backup tape to the start of the SFS directory data. VMBMCOPY has been modified to update and, if it is necessary when copying a backup from a previous release, to add these new fields to DIRH records that it copies.
Use the HELP VMBACKUP NOTICE command or press the PF2 (Notice) key on the HELPABC1 screen to display a Legal Notice.
The XRESTORE command provides system administrators with a simple line-mode method to restore an SFS file space that was previously deleted without having to resort to manually coding a TPI job, and lets users restore files from minidisks and directories using a line-mode command.
Use this command to select files that you want to restore from minidisks or directories, and to select deleted file spaces that you want to restore. These requests are submitted automatically unless the REPORT option is specified.
The QUERY STORAGE command allows system administrators to dynamically monitor CA VM:Backup virtual storage usage.
Use this command to display or stack message VMBSYS0075I, "Maximum virtual storage used since VM:Backup was started was 751M out of 1.0G bytes."
The QUERY BACKUPS command provides operators a line-mode method that shows the status of each running backup job stream’s progress. These statuses help operators determine whether all is well or whether the job is waiting for a quiesce, tape mount, or other event.
Use this command to display or stack information about the progress of the backup jobs that are currently running.
The TRSIZE startup option allows the changing of the default size of the CA VM:Backup internal trace table, enabling more effective troubleshooting by CA Support.
Use this option to change the size of the CA VM:Backup internal trace table from the default size of 256K to a different size. This option is useful when CA Support determines more trace table data is necessary to help find the cause of a problem.
CA VM:Backup is now enabled to receive shutdown signals from CP, allowing graceful shutdown of the CA VM:Backup server during system shutdown processing.
When CA VM:Backup receives a shutdown signal from CP, the END command is invoked.
