Operating system CentOS 7
NetVault version 11.0
Using NetVault add device option and selecting “Single physical tape device” to a smart client we see “WARNING! No standalone tape drives were found on the selected client”
Logging onto the Linux CentOS 7 smart client we issue the following commands
cat /proc/scsi/scsi < FIGURED YOU MEAN THIS?
==================
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: QUANTUM Model: ULTRIUM 5 Rev: 3180
Type: Sequential-Access ANSI SCSI revision: 06
lsscsi -g
=============
[0:0:0:0] tape QUANTUM ULTRIUM 5 3180 /dev/st0 -
This show that the tape can be seen but there is no SG driver loaded.
We issue the “modprobe sg” command and issue the command below again we see that the SG driver is now loaded.
lsscsi --generic
[0:0:0:0] tape QUANTUM ULTRIUM 5 3180 /dev/st0 /dev/sg3
The tape drive will now add in NetVault but a reboot of the smart client would see the sg driver no longer loading and the tape drive unusable.
