Status Codes
e. On UNIX systems, look at the /usr/openv/netbackup/db/media/errors
log (which is also included in the
/usr/openv/netbackup/bin/goodies/support script output) for a drive
that is frequently producing errors.
Status Code: 84
Message: media write error
Explanation: The system’s device driver returned an I/O error while NetBackup was
writing to removable media or a disk file.
Recommended Action:
1. For additional information, check the following:
◆ NetBackup Problems report to determine the device or media that caused the
error
◆ System and error logs for the system (UNIX)
◆ Event Viewer Application and System logs (Windows NT/2000)
2. If NetBackup was writing backups to a disk file, verify that the disk has enough space
for the backup.
For a catalog backup to a disk path on a UNIX system, you may be trying to write a
image greater than two gigabytes. File sizes greater than two gigabytes is a limitation
on many UNIX file systems. Tape files do not have this limit.
3. If the media is tape or optical disk, check for:
◆ A defective or dirty drive, in which case, clean it or have it repaired (refer to the
tpclean command for robotic drives).
◆ The wrong media type. Verify that the media matches the drive type you are
using. On an optical drive, the platters may not be formatted correctly.
◆ Defective media. If this is the case, use the bpmedia command to set the volume
to the FROZEN state so it is not used for future backups.
◆ Incorrect drive configuration. Verify the Media Manager and system
configuration for the drive.
For example, on UNIX the drive could be configured for fixed mode when it must
be variable mode. See the Media Manager Device Configuration Guide for more
information.
