4. Try to launch the X Window version of Yosemite Backup. It should work properly.
Recognizing LUNs
Some Linux systems do not immediately recognize all LUNs for a library.
To verify that all LUNs are recognized
1. Enter the following command
“cat /proc/scsi/scsi”
2. If a LUN does not appear, force the system to recognize it with the following command:
echo “scsi add-single-device w x y z” > /proc/scsi/scsi
Where the parameters are as follows:
• w is the host adapter ID where the first adapter is zero (0)
• x is the SCSI channel of the host adapter, where the first channel is zero (0)
• y is the SCSI ID of the device
• z is the LUN number of the missing LUN, where the first LUN is zero (0)
3. Once the device has been detected properly, stop and restart Yosemite Backup and the Yosemite
Backup service if it is running.
