Hi
We had alway CDI on "SCSI Commands" now we upgrade a Falconstor VTL with RHEL5.1 from 4.0 to 5.1
Since then the couldn't Backup anymor your Red Hat Linux und Solaris but the Windows still worked normal.
The error message was:
Nov 11 09:57:14 bwbckse1zhh logger: NetWorker media: (alert) device "/dev/nst3": serial number mismatch, check system device ordering. Expected "Serial Numbers:WWNN=500630323142AAAA:ATNN=HP Ultrium 3-SCSI 8AU5S0021B:8AU5S0021B", found ":WWNN=4850202020202020:8AU6400238"
Then we disabled CDI on all Drives.
Now the Backup is working again normal and we haven't seen this errors anymore in the Logs.
For what is CDI?
Is there any disadvantage because we disabled CDI?
What are the recommendet settings for CDI: "SCSI Commands" or "Not used"
What are you using?
Thansk for your help
