Configuring new Library

[r1]

I am not a unix person. We are getting a new library with 4 LTO5 Drives . This is FC Library , no scsi or switches involved . All direct attached FC . The master server is solaris 10 . What commands , or steps i need to take to configure the Master Server solaris 10 version to see the drives and robot .

I know how to run the wizard in NBU but what do i need to run to scan for new devices and detect the new library and drives . any tips and asssiatnce is greatly appreciated . Thanks

Please remember to delete old devices from NBU before adding new ones.

First cleanup existing device entries:
# cd /dev/rmt
# rm *

This command will scan for devices and create entries:
# devfsadm

Verify device entries:
(while still in /dev/rmt)
# ls -l *cbn

If the correct amount of tape drives are not seen, speak to your hardware and OS support guys...

Check to see if NBU can see devices:

# /usr/openv/volmgr/bin/sgscan

If the same devices listed in /dev/rmt are not displayed, you will need to rebuild the sg driver:

# cd /usr/openv/volmgr/bin/driver
# /usr/openv/volmgr/bin/sg.build all -mt <15> -ml <1>        (use output of /dev/rmt listing to determine targets and luns)

Install the new sg driver configuration:

# /usr/bin/rm -f /kernel/drv/sg.conf
# /usr/openv/volmgr/bin/driver/sg.install

Check/verify:

# /usr/openv/volmgr/bin/sgscan

Detailed 'sg.build' info in http://www.symantec.com/docs/TECH71073

Hi Champ,

For sharing TL amongst hosts you need to have that TL visible to hosts which you want to have sAN based backup.

For Eg. If you want 4 hosts to use same TL then all four hosts need to see TL.

This can be achieved using SAN SW.

hope this helps...
