Sections ("s") in Itanium disks

[Arunvijai_4]

Hi All,

This is related with my previous question on "s" in 11.23 disks. http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=967274

I would like to know the following stuffs,
1) What command(s) do you use to administer these disks, set up slices, etc. (equivalent to the Solaris "format" command)?

2) What commands or system calls do you use to get information on these disk slices (equivalent to the Solaris read_vtoc() call)?

3) Can we have different FS on a same disk ?

Thanks,
Arun

Hi Arunvijai
ad. 1) Group commands efi (efi_cp, efi_fsinit, efi_ls, efi_mkdir, efi_rm, efi_rmdir), remember thats devicefile is cXtYdZsV (V - 1,2,3... - slices)
ad. 2) efi_ls -d /dev/rdsk/cXtYdZsV
ad. 3) Yes

Hi,
some additional commands:
1. idisk - equivalent to Solaris "format"
2. idisk -p /dev/rdsk/cXtYdZ
and diskinfo for each partition (slice)
diskinfo /dev/rdsk/cZtYdZs1
3. yes

look at my script for doing mirror I think will be useful:

Here's a nice checklist on mirroring root disk on Itanium systems:
