Moving mount point to another server

Hardware:2 Alpha Servers - GS60E
OS:Tru64 Unix 5.1b
File System: AdvFS
I have a fileset/mount point on server A that I want to delete. I then want to make the disk/partition (that this mount point was using) available to server B. I have no knowledge of the physical disks on my systems except that there are some disks mounted in each server's cabinet and that we have a StorageWorks RAID array which, I assume, is being used by both servers. How can I do this, ensuring that I don't waste any disk space in the process?

Re: Moving mount point to another server

You can find the disks/partition/LSM volumes that your AdvFS domain uses by issuing:
#showfdmn

Say you want to use dsk1a that is currently used by this domain, you can issue 'rmvol' command to remove this disk from the domain. No need to remove the fileset.

'addvol' requires license. The data from dskla is automatically migrated to the other disks that are part of the domain.

Re: Moving mount point to another server

First locate physical device of advfs domain:

1. # df |grep
sample: / root_domain#root
here root_domain is the domain

2. # ls -la /etc/fdmns/
output could be:
/dev/disk/* < physical disk
/dev/vol/* < lsm disk

3. in case of physical disk:
# hwmgr -show scsi |grep
leads to scsi-bus/id. you can use the
hwmgr to locate the disk by flashing the
light (man hwmgr)

4. in case of lsm disk:
# voldisk list
leads to physical disk within lsm
go to 3 to locate physical disk.
It is necessary to deconfigure lsm disk
prior of physical moving!

In case of a raid-controller/storage disk it will be necessary to use additional commands on the storage controller itself to prepare moving of disk.

I contacted HP support directly so that I could get a more detailed solution.
