@iaw,
Could you please give more detail about your SAS disk?
Is it a HW raid? if so which level (0,1,5,10)?
How many disk do you have locally and what are their capacity (size)?
Do you plan to configure it as standalone sesrver or Cluster node with Veritas Storage fondation ?
1. Best practices (basic LPIC-1 objective) in partition layout for system is:
/ (eg. 50Gb)
/var (eg. 30Gb)
swap (eg. 16Gb)
optionally, you can create a seperate partition for /home
2. You must create a seperate partittion for the Catalog. We have actually design a partition of 200Gb for the catalog. It depend also on how much policies you plan to have, for this you need to analyse your need for the sizing (See netbackup Admin guide).
When you install netbackup, the catalog will be located under /usr/openv/netbackup/db. Once installed, you need to create a symbolic link to your dedicated partition for the Catalog. Example, this is my symbolic link the catalog location which is on a seperate partition:
[root@master]# ls -ld /usr/openv/netbackup/db
lrwxrwxrwx. 1 root root 21 May 14 14:21 /usr/openv/netbackup/db -> /catalog/netbackup/db
[root@master]#
3. Netbackup binaries will be located under /usr/openv/netbackup (/usr/openv is the top directory used for it) directory. You need to have enough space (see point 1 / sizing). Our actual space used for /usr/openv is 16Gb:
[root@master]# du -hsc /usr/openv
16G /usr/openv
16G total
4. If you plan to configure it as a cluster node, i recommend you to read installation guide for netbackup in Cluster and also use Veritas storage Foundation as Cluster software. Don't use LVM for your root file system if you have a RAID hw (eg. Fujitsu RX300 comes with local disk in RAID1 HW through LSI controller)
If you have more questions or need more details don't hesitate to ask ;-)
