How to check partitions on Integrity HP-UX

To all,

I have been doing some reading and here is what I have come up with so far. I just setup a new HP-UX 11.31 and noticed that the root disk is /dev/disk/disk5_p2 which I found is for HP-UX and then there are Slice 1 and Slice 3. If I want to add a mirrored drive I want to make sure that Slice 1 and Slice 2 are the same size. So take for instance I dont know what the size is of those partions. Is there a way to find out what the actual size is of those Slices?

I have seen "examples" of partitioning a drive, which looks like the following.

3
EFI 500MB
HPUX 100%
HPSP 400MB

The documentation says this is an example, so I want to know for sure what the size was that was used on the original disk. How do I find that out?

Thanks in advance,

Todd

Re: How to check partitions on Integrity HP-UX

Hi,

Meaning of this lines
3
EFI 500MB
HPUX 100%
HPSP 400MB

The first entry specifies the number of partitions to create that is 3.
The second specifies an EFI partition of 500 megabytes.
Next entry specifies a HPUX partition consisting of all the remaining space on the disk after the EFI partition has been created.
Tha last is specifies one HPSP partition of 400MB.
