Boot disks in SAN
my question wishes some replies from your great experience on HP-UX systems.
What are issues to have boot disks (boot disk + mirror) in SAN (Storage Area Network)?
I think about a slow boot (slower than boot disks inside the machine) and performance issues on network.
It also could be another point of failure for Disk Array.
Other hints according to your experience?
Thanks and best regards,
Ettore

Re: Boot disks in SAN
Same here, no experience. It can be usefull if you have more than one identical server in case of desaster recovery.
I would prefer local disks for swap.
HTH,
Gideon

Re: Boot disks in SAN
Maybe the whole network could be a point of failure (eg: cables, NIC)
You may want to implement a redundant boot nic.
eg.
MirroredDiskArray

Controller1-Controller2
| \ / |
| \/ |
| /\ |
| / \ |
SANswitch1 SANswitch2

NIC1 NIC2
| |
Server
Any comments are welcome.
Peace, R>

Re: Boot disks in SAN
Swap space issues are meaningful but you may use local swap.
Maybe you can have problems upgrading NIC firmware or nic driver. Don't know how is singel-user booting tru san-storage but the server should see the fiber like a scsi device (but I'm not sure about it!!!)

Re: Boot disks in SAN
Running the system disks on the SAN is a hot topic for OpenVMS and Tru64 Unix systems, because both can use a common system disk within a cluster. It is less of a problem, because the AlphaServer console has good boot support and diagnostic tools.
It limits the system management a little bit, because patches are rolled out only once. The downside, of course is, that you are now depended on one copy of the system disk, but we all know that breakfast is not free ;-)
You could use value-added services on the storage array like snapshots or clones to protect your data or make it available for tests. Not every operating system has a powerful volume manager.
A local disk with a pre-installed operating system and up-to-date drivers is still a nice thing. It adds additional diagnostics for some systems and you don't have to pull your system up from CD-ROM - I have seen cases where the drivers on the CD-ROM were too old and I could no longer access a storage array with recent firmware.
Roberto,
if you attach your drawing as a .TXT file there is less reason to curse ;-)

Re: Boot disks in SAN
You need to check with your SAN switch, SAN disk, and server providers to determine the interoperibility issues.

Re: Boot disks in SAN
I am currently prototyping SecurePath 3.0D - which has support for boot,swap and dump on SAN devices(including EVA). Despite it being withdrawn twice already, I am finding it remarkably robust and fast too. We will be rolling it to production very soon once we get an Okay from HP on SecurePath 3.0D being once more on G.A.
Harry,
What SAN environment are you booting off your servers? DO you use SecurePath/AutoPath or simply PV links?
Thanks!

Re: Boot disks in SAN
And HP "supports" this environment?
I suppose you use PVLINKS for Path protection?
