I have a DS20E (Tru64 4.0f) with LSM rootdg on disk rz25 and a second disk group on rz0 for our application data. The LSM config database partition is rz25b.
The system is being retired and the replacement server has different physical SCSI bus layouts, so that the root disk becomes rz9 and the data disk becomes rz20.
To migrate from one server to the other I was hoping there would be some simple method of reconfiguring LSM on-the-fly rather than having to reinstall Tru64 and reconfigure the system from scratch. On the LSM volumes there are AdvFS filesets, some of which are hosted as TruCluster services on shared SCSI between nodes so if possible I would like to just change the LSM to physical SCSI mappings and the rest would just follow.
I've tried editing /etc/vol/volboot to point to the new location of the LSM database (rz9b) and booted the root disk on the new server. But the LSM daemon doesn't start up.
Any ideas how to change the underlying physical devices which LSM is looking for, without stripping and rebuilding the entire system?
thanks.
