How did you mirror those? If you did through "dd" command, you just have to install that drive and the system will boot as normal. If it's through Mirror/UX software, you may need to interrupt the boot process and override the quorum check (hpux -lq). Make sure to check the LIF area of the mirror disk and see if all files are set properly.

I've done this with K Class servers and hot pluggable disk drives. Is yours also hot pluggable? If not then you'll have to power down. Once installed power up and interrupt the boot up, 'sea ipl' at the BCH and verify that the server knows its bootable. Once verified 'bo p0'.

at PDC prompt> sea ipl

Bo [path of disk] isl

at ISL prompt > hpux -lq.

It should work if the servers are identical and you have done mirroring of all LVs and updated the LIF area.

Hi,

One thing to remember is that the 2nd server will be truly identical to the 1st server, so it will want to come up with the same hostname and IP address. You will probably need to boot it without it connected to the LAN, change the hostname and IP address [and anything else specific to it], shutdown, connect to the LAN, and reboot.

It's the kind of thing that I would forget about until the 2nd server had booted and the 1st server started complaining. :)

John makes a very good point there. You should run 'set_parms initial' after boot and verify all the other settings.
