Disk partitions and AdvFS

Is there any good reason to carve up partitions to utilize with AdvFS domains vs. using 1 whole disk partition per domain?

i.e.

foo_domain -> dsk75a
bar_domain -> dsk75b
car_domain -> dsk75d
...

vs.

foo_domain -> dsk76c
bar_domain -> dsk77c
car_domain -> dsk78c

We have a system set up to utilize partitions vs. the whole disk approach. It seems like a bad idea to me (i.e. it seems better to me to do all partitioning at the SAN level). Is there any good reason to do it using partitions at the OS disk level?

Thanks.

Using the whole disk ("c" paritition) is always better.

Re: Disk partitions and AdvFS

You always get better performance balancing the I/O between multiple disks, instead different partitions.

You need a different partition when you want to isolate the data. So a corruption on one domain wont affect the other, but a domain crash is not very common.

You can use one partition, one domain and various filesets to get a better utilization of disk space.

Re: Disk partitions and AdvFS

Hi,

The answer is it depends upon the business requirement. On a production node highly unlikely. But when we get into test and dev nodes... it helps when you start scripting the installation of various oracle instances etc...

Hope this helps.
