Drive replacement
hi,
I have a netbackup 6.5.4, we have configured one of the server as a san media server and it is hosting Production SAP database. we replaced a drive which was assigned to it, it has solaris 10 OS
We have rezoned with new WWPn number to the server and delelted old zone.
The os team says the drive is detected, now do we need to run SG BUILD as it is not detected by netbackup.
Kindly let me know the steps needs to be followed on SOlaris after driver replacement on SAN media server.
Thanks,
1. To determine if a sg driver is loaded
/usr/sbin/modinfo | grep sg
2. To remove the sg driver
/usr/sbin/rem_drv sg3. To reinstall the sg driver
/usr/bin/rm -f /kernel/drv/sg.conf
/usr/openv/volmgr/bin/driver/sg.install
4. Invoke the following two commands to run the sg.build script to create target IDs and LUNs:
cd /usr/openv/volmgr/bin/driver/usr/openv/volmgr/bin/sg.build all -mt 15 -ml 1
The -mttarget option and argument specifies the maximum target ID that is in use on the SCSI bus
(or bound to an FCP HBA). The maximum value is 126. By default, the SCSI initiator target ID of
the adapter is 7, so the script does not create entries for target ID 7.The -mllunoption and argument specifies the maximum number of LUNs that are in use on the SCSI bus
(or by an FCP HBA). The maximum value is 255.5. cp /usr/openv/volmgr/bin/driver/st.conf /kernel/drv/st.conf
6. cp /usr/openv/volmgr/bin/driver/sg.conf /kernel/drv/sg.conf
7. Verify that the system created the device nodes for all the tape devices by
ls -l /dev/rmt/*cbn
