There are plenty of posts in this forum regarding similar problems.
Search this forum for the terms "persistent binding" and "tpautoconf -report_disc".

To answer the questions (although you will need to followed the outstanding advice from 'Marianne the Great' and 'SDO the Incrediable' :0) - the eaierst way to 'UP' drives ...
vmoprcmd -up <index number>
The index number is the number on the left. So here it goes from 0 - 7
However, until the original paths come back, or, the drives are deleted and reconfigured with new paths, you cannot 'UP' the drives. As stated, the operating system has lost connectivity to the drives, this needs troubleshooting and fixing at the OS level first.

You should've noticed the MISSING_PATH next to the OS path.
It is in big letters for a reason.
Something happened at OS or hardware level - faulty hba, faulty cable(s), faulty gbic, etc. etc...
Check physical connections.
Check /var/log/messages file for hardware errors.
Only return to NBU when the the OS can see devices with this command:
cat /proc/scsi/scsi
Confirm as follows:
/usr/openv/volmgr/bin/scan
If device paths are different to those in NBU config, you will need to delete NBU config and run Device Config Wizard again.
Read up on Persistent Binding for the make/model hba in this server.
