In the "typical" processing, the RMU stuff runs before the BACKUP stuff and thus allows the BACKUP to capture the freshly-generated RMU archives, obviously.)I've put together a non-RMU backup from somebody http://back2cloud.com/parity-error/parity-check-parity-error-system-halted.php

Hence its good to add some value between 0 to 100 for /GROUP qualifier instead of 0. The 4 databases are quite large (between 55.10E6 blocks and 65.10E6 blocks) In 4 months time I replaced 4 other tapes and experienced about 20 Parity errors on 4 different drives Generated Mon, 24 Oct 2016 01:38:55 GMT by s_wx1011 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: Connection The following disables the BACKUP mechanisms used to recover from tape errors, and also allows silent data corruptions:BACKUP/IMAGE/NOALIAS/NOCRC -/GROUP=0/BLOCK_SIZE=65024 -/MEDIA_FORMAT=COMPACTION -/NOREW/NOREC/IGN=(LABEL,INTERLOCK,NOBACKUP)- /LIST=DISK$WORKCOBOLFTP:[BACKUP_LISTINGS.NRCAVA]DGA241_200909111707.LIS -DISK$RMADSK01: - mt:DGA241.BCK Whomever coded that "trusted the drive" click here now

The third would cause the drive to continuously try to complete loading!!! The system returned: (22) Invalid argument The remote host or network may be down. You can use the default value i.e. 10 should be moderate./IGNORE=INTERLOCK allows BACKUP to save a file that is currently opened for write or exclusive access.

Data that is in user or system buffer in memory will not be saved. Note that this is an obsolete feature with modern tape drive that have Reed Solomon ECC built into the drives. If the error message does not indicate a media or parity error, you can retry the backup job in a different MARLIN tape drive. Add/Remove Software on Control Panel 5.

VMS: 7.2-1H1 / Rdb : V7.0-6.2 / SLS V2.9 F Performance inprovement was spectacular : In some cases we went from a 4 hour 30 minutes to about 25 minutes of SCSI Parity Errors 8. Whomever coded this effectively implemented the archives to look nice and to occupy storage media and to keep a tape library busy, but I'd be willing to bet that the recovery If the problem is a media /parity error, you must resubmit the job.

To find out what went wrong with a backup job, locate the following >LOG file and look at the end of the file.

A couple of questions:Whomever wrote this procedure coded some stuff I would not have coded. Parity error on Backup to tape 13. Of these, 3 were bad. And these tapes are NOT cheap !!!

Or DECTERM session, or Simply type the command exactly as shown in the .LOG file. navigate here Notify VMS systems support. After the tapes have been loaded in to the new VMS drive ($30$MKB100 in the example above), the entry can be released to actually start the VMS job. We received a 9 track magnetic tape the other day which has a tape parity error about 80% into the file.

HELP!? 7.

That way, I had a couple of recent copies on disk, and only needed to pull a tape from the archives on rare occasions. Click to select another procedure ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: Connection to failed. Use it. The system returned: (22) Invalid argument The remote host or network may be down.

Backup is not the correct tool unless the database is down, and the database file is static. The size of the XOR redundancy group is controlled by the /GROUP_SIZE qualifier. About 5 tapes were faulty already during the first initialize in SLS and had to be replaced. this contact form Sessionj window into the other available KEA!
