5. If max_scsi_luns=2 does not appear, you did not update the configuration file correctly. Start
over with step 1 above.
6. Verify that your system detects the library, using the following command:
cat /proc/scsi/scsi
To update the configuration file and verify the configuration (GRUB)
1. Locate the grub.conf file. This file may also be called menu.lst. Possible locations include /boot/grub
and /etc.
2. Add the following text to the end of each kernel image line in the grub.conf file:
max_scsi_luns=2
Each kernel image line will read similar to the following:
kernel /vmlinuz-2.2.6-2 ro root=/dev/hda3 max_scsi_luns=2
3. Save the file and reboot your system.
4. Verify that the change has been implemented, using the following command:
cat /proc/cmdline
5. If max_scsi_luns=2 does not appear, you did not update the configuration file correctly. Start
over with step 1 above.
6. Verify that your system detects the library, using the following command:
cat /proc/scsi/scsi
IDE/ATAPI Support
Yosemite Backup supports the use of IDE/ATAPI tape devices. If your Linux distribution compiled the
ide-tape.o module into the kernel, update the configuration file and verify the configuration to
access these devices.
NOTE: When Yosemite Backup runs, it loads the ide-scsi module. This may cause the ide-cdrom
module to fail to load, which may affect CD operation. To work around this problem, mount the CD as a
SCSI device, even though it is an IDE device.
To update the configuration file and verify the configuration (LILO)
1. Add the following line to the end of each boot selection section in the /etc/lilo.conf file:
Master on primary IDE append=“hda=ide-scsi”
Slave on primary IDE append=“hdb=ide-scsi”
Master on secondary IDE append=“hdc=ide-scsi”
Slave on secondary IDE append=“hdd=ide-scsi”
2. Update your system configuration, using the following command:
lilo
3. Save the file and reboot your system.
4. Verify that the change has been implemented, using the following command:
cat /proc/cmdline
