We are running 6.1R1, and we are seeing the following symptoms ever since installing Veritas Netbackup and a new Qualstart AIT tape library. The errors occur when a tape change occurs in the middle of a backup. The 'solution' below seems to say that Veritas is timing out waiting for NDMP to load the new tape. Does anyone know how to increase this timeout in NetBackup?

Thanks,

Moshe

Title: NDMP backup error message: Device 0b.4: Sense Data no error - (0x0 - 0x0 0x2) - NetApp filer

Problem Environment: NetApp filer F85 F800 series F700 series F600 series Data ONTAP 6.x NDMP backup software ONTAP 5.3 and earlier versions returned a 'SCSI bus reset' then retried the command

Problem Description: Error message: [scsi.cmd.checkCondition:error]: Device 0b.4: Check Condition: CDB 0x10: Sense Data no error - (0x0 - 0x0 0x2) Error message: Device 0b.4: Sense Data no error - (0x0 - 0x0 0x2)

Fix: 1. Check that a tape is loaded and ready (ONLINE). 2. Check the configuration of the NDMP backup software. If using a robotic tape library, then make sure that the backup software is configured correctly to work with the library.

This symptom can also be seen when a dump or restore spans multiple tapes, and the NDMP software times out waiting for the tape change. Legato's default timeout is 30 seconds, and Veritas' default is zero seconds. In this case, the fix is to increase the timeout in the NDMP software. Last updated: JUL 2001

Cause of this problem: An application or process accessing the tape device has made an attempt to write file marks past the end of tape. NDMP backup software is not configured correctly to work with the tape device or library.
