72 GB root disk support ( L Class)

hi,

I have entered into a situation where i have to load HPUX 11.0 in an 72 GB root disk. The server is L-1000. Is this supported ? Please let me know this so that i can go ahead with procuring a 72 gb disk.

thanks in advance

Mahesh

Gee, that's a waste. Even 18 GB can be too much. But it depends on your swap size which depends upon your physical memory and swap's calculated to be 2 to 2 and 1/2 times physical memory.

Here are some rough file system sizes for a 4 gb disk on the smaller end of the range that have worked for me in the past, and some higher end numbers that have also worked. Note, they can be, even higher, but then you'll have to worry about fragmentation.

(* NOTE: The HP minimums are a bit smaller than this. *)

lvol1 - / ~ 100 - 250mb
lvol2 - swap ~512 - 2 GB
lvol3 - /stand 100 - 250mb
lvol4 - /home - 20mb - 1024mb
lvol5 - /opt - 800mb - 1024mb
lvol6 - /tmp - 512mb - 1024mb
lvol7 - /usr - 800mb - 1024mb
lvol8 - /var - 800mb - 1536mb

That's ~ 8 GB. With the other ~64 GB you could make a nice working file system for dba types, or a crash dump file system. But dumps are only 400mb unless you want the all of physical memory dumped out.

A lot of things don't work well if you start using vg00 for data or file systems other than the core O/S. Ignite and Service Guard for instance. And the one advantage I could see might be better performance, as long as you don't get real big and fragmented.
