Windows 2003 Standard server with a Benchmark DLT tape drive that backs up a couple of 2003 Servers and a Netware 6.5 Server. Most of the time everything is fine but sometimes (4 times in the past 3 weeks), the job will fail during the verify of the first volume; the D volume of the machine Backup Exec is installed on. The specific message in the Backup Exec log is "Storage device reported an error on a request to read data from media.
Error reported: The semaphore timeout period had expired." All other BE jobs work fine.
Stops errors are generated in the application event viewer are event id 33152 (Adamm Mover Error: Read Failure!), 33152 (Adamm Mover Error: Read Not Ready Failure!), 57665 (Storeage device reported an error on a request to read data from media) and 34113 (Backup Exec Alert: Job Failed; the backup storeage device has failed). These 4 appear everytime the job fails.
Various media has been used and the DLT tape drive is regularly cleaned. All updates have been applied to 2003; the build of Backup Exec 10.1 Rev 5629.
Let me know if I can provide additional information.
All replies appreciated.
