Re: bdf size change in 11i v2 & v3

Not possible to determine because there are several operating environments (OE):

-- Base OE
-- Virtual Server OE
-- High Availability OE
-- Data Center OE

You did not indicate what hardware you have (Itanium or PARISC -- hint: model command).

You may also have several additional products stored on your 11.23 system plus all the old patches in /var/adm/sw which are required to remove a new patch. There are a number of additional features on 11.31 that will require additional space.

So start with a minimum root volume size of 36GB (plus another 36GB disk for mirroring which is mandatory for production). Then using the bdf output, add 20% more space to any filesystem that is less than 50% utilized. For usage between 50% and 75%, increase the new size by 50%, and for 75% and larger, double the new size.

If you have only purchased the Base OE, then purchase Online JFS and Mirror/UX as these are also minimum requirements to run a production system. These products are included in the other environments. Here are the environments:

If you are installing 11.31 on a machine that did not come pre-installed with 11.31, be sure to go through the checklists:

-- Will your system run 11.31?

-- Is the firmware up to date for 11.31?

You'll need a minimum of 1.5 GB of RAM to run 11.31, double or triple that amount for databases such as Sybase, Informix or Oracle.
