Thank you all for the input.
There are some ways to do this, but as the servers might be different
makes the process more complex, with booting from alternative media, CD
or net. As it is not a Sun supported solution we are going to look at a
Cluster solution or maybe using LDOMs.

Maurice

Subject: boot different server from disk

I have a T2000 server (call it A) booting from a SAN disk. I want to
boot another server (B) from this disk, after server A is shutdown. This
server B presents the device at a different device path. How can I get
around this?

I have tried to boot server B in single user mode to make changes to
/etc/path_to_inst and the /dev links, but the root disk seems to be
read-only, while the mount command  shows it is read-write:
/ on /pci@7c0/pci@0/pci@8/SUNW,qlc@0/fp@0,0/disk@w210000d0231e6fe6,0:a
read/write/setuid/devices/dev=1d80000 on Thu Jan  1 01:00:00 1970

Can you boot a server on another servers disk?

Regards,
Maurice
