Re: root disk partitioning for mirroring

They are NOT partitioned for mirroring.


On a Integrity boot disk are 3 partitioned, 1 for EFI, 1 for HPUX, 1 for Service tools.

You need another disk for mirroring.

Hope this helps!

Re: root disk partitioning for mirroring

Hi,

It is not like that we are partitioning root disk only for mirroring.
For integrity servers we have to keep the root disk in three partitionings like in this manner
The boot disk of IA machine got 3 partition,

s1 - EFI
s2 - OS
s3 - HP support tools

Re: root disk partitioning for mirroring

The EFI area is FAT32 for the OS loader (common INTEL standard), the HPUX partition is under LVM/OS control.

Hope this helps!

>> Is the partioning is because of intel platform?

Yes, it's Intel specification (default).



HPSP holds several tools, e.g. offline diagnostics, offline firmware update tools, several EFI tools. etc ...

Hope this helps!

Re: root disk partitioning for mirroring

This is the link to the offline diagnostic CD image:

You can install these tools in HPSP area, but normally you never need it there.

Hope this helps!

Re: root disk partitioning for mirroring

And finally - if you choose hardware mirroring via the controller, the complete disk (all partitions) will be mirrored - if you use LVM mirroring, only partition 2 will be mirrored, so you need to take care about partition 1 (and maybe 3) yourself.

Hope this helps!
