Mirroring Root Disk on itanium server

Waqar Razi — Thu, 14 Aug 2008 11:36:45 GMT

I have a question about mirroring root disk on itanium server about the partition we create using idisk utility.
How can we check the size of the current partitions on the current root disk. We need to make exactly the same size partition as on the current root disk, Right? Please send me the commands to look for the existing configuration. The HPUX version is 11.23 and it is BL860 itanium based server.

By partitions, I mean efi, hpux and hpsp partitions.

diskinfo will show you the size of all 3 partitions:

# diskinfo /dev/rdsk/c1t14d0s1
