Cold Install on New 3410

HPUX 11iv2 PARISC 3410

Hi all,

I am doing a cold install (11iv2 Foundation) on a new 3410. The 3410 has 3 73GB internal drives and no other attached storage. 73GB should cover disk needs. How should I configure the 3 drives..mirror 2 and keep the 3rd for a hotspare? Stripe? What are my options with the foundation version of the the OS? Does it include Mirror/UX? Thanks in advance!

Shalom Chris,

Mirror/UX is not included in base 11iv2, which you have.I recommend it.

You could go VxVM instead of LVM in which case you get mirroring for the rootvg or boot volume group.

Either way I recommend:
1 Boot disk, everything with the possible exception of swap mirrored to a second drive. The third drive can be one gigantic scratch filesystem or an Ignite Image server.

Unfortunately Foundation OE does not include MirrorDisk-UX. The only suggestion I can make (since you're installing fresh) is to just make use of VxVM. Use VxVM to manage your 3 Disks as members of rootdg and you have mirroring for free (that is if it has not changed yet. qith 11.11 VxVM 3.5, you can mirrror ONLY the OS/rootdg disks.)

I trust your server will be simply be an APP or WEB server. In this case,my suggestion:

2x73GB as OS disks and Apps tree (mirrored using VxVM). The extra 73GB disk, you can use as hotspare..

If you have some budget, you should decide either to buy a mirror/ux licence or (why not) a smartarray card and configure a raid5 over your three disks.

And here's how I would carve my rootdg under a 2 disk-mirror/1 hotspare VxVM managed system:

standvol - 512MB /stand
swapvol - 16GB
rootvol - 8GB /
optvol - 32GB /opt
varvol - ~ balance 10GB /var
tmpvol - 1GB /tmp

/opt should be enough to house software tree and logs for most app servers, middleware or web server tree.

Wow...I'm glad that I asked.

Does VxVM impact the usage of make_tape_recovery and make_net_recovery? I am used to depending on them for system recovery.

Nope.. not at all.

Ignite versions 5.35 upwards fully supports VxVM.

Just a note that VxVM is different than LVM so if you're only familiar with LVM, the learning curve may be a bit steep. In that case, purchasing it will less stressful.
