A Stand-Alone Restore (SAR) is performed whenever the MVS system is both not operational and not ipl-able. SAR is done only by someone from Technical Services.
Before any type of recovery action such as a Stand-Alone Restore is performed, as much information as possible must be gathered for the Systems staff to be able to debug the problem. This information is to be recorded in our REMEDY database. When MVS crashes, the operator should minimally record specific items. Some of these items are:
Are there any "symptom" symbols in the lower left-hand corner (boxed 4 with an "A" over a dash connected to a solid box is normal; all other symbols are abnormal)?
If console is not operational, is the alternate MVS console operational?
Incremental backups are taken daily and full-volume backups are taken weekly. In addition, the sysres volume, OS9RES, is full-volume-dumped daily in job BKPRES00. Stand-Alone Restore uses only full-volume dumps.
Backup listings may, depending on the time of day, be located in the first floor printer area (office 116C).
Job BKPRES00 is run daily and full-volume dumps the sysres volume. If you are restoring the sysres volume it is usually best to find the most recent BKPRES00 listing and determine which backup cartridges to use for the SAR. Copy the tape volume numbers (keep them in sequence) from this listing.
If you choose not to use BKPRES00 output to restore from job BKPFDR contains a listing of the latest FDR/ABR backup tapes for each dasd volume. Locate the dasd volume (to be restored). Copy the tape volume numbers (keep them in sequence) from the same line (top line) as the dasd volume; this is always the most recent full-volume backup (but it may be as much as a week old).
Ask the computer operator to retrieve the desired cartridges.
Weekly full-volume dumps (i.e., the cartridges) are stored in a safe in Fronczak Hall. All other backups (including the daily BKPRES00 cartridges) are in the tape library.
MVSP03 (F1E), ADMN03 (F16), BSON33 (D03), RFP003 (FC2) & RF0003 (FE2) contain SAR IPL text.
SAR IPL text is also on the FDR/ABR installation tape maintained in office 335 with the FDR/ABR documentation. It is much easier and faster, however, to use the customized SAR IPL text on dasd.
Sometimes this command fails with a reason of "unauthorized", do not worry about it. Continue with:
This keeps VM from trying to use the drives during the SAR.
This will take about 3 seconds and produces no messages.
You'll need to know the address of the dasd volume being restored to and the tape drive address, if ofther tan 791-792 / 991-992.
Merely depress "ENTER" for options you do not wish to change.
Console messages will tell when to mount subsequent tapes. A message on the console will indicate a successful restore.
Return to the UBVM VM logged-on account UBMVS and type:
Change the address of the sysres volume.
