Creating mirror disk---- IPF server

[Rgomes]

Hi All,

How can I mirror the root vg on rx5670 server. It has little bit different procedure than PA-RISC servers. What I can't understand
the first step:

# vi /tmp/partitionfile
2
EFI 100MB
HPUX 100%

What are these 3 entries?

Thanks all of you,
Richard

Hi Richard,

Here is a good doc from the database,

Hi Robert,

Thanks for your prompt reply and the link!
I can still see these 3 lines as the first step:

# vi /tmp/partitionfile
2 <------------ ??
EFI 100MB <---EFI filesystem 100MB,is it ??
HPUX 100% <--- ??

You know what are these? Can you pls let me know.

Thanks again,

Richard

Richard,

lines of the partitionfile:
# of partitions to create
TYPE_of_partition SIZE_IN_MB
TYPE_of_partition PERCENTAGE_OF_REMAINING_MBs
....

e.g. could look like
8
EFI 500MB
HPUX 1024MB
HPUX 1024MB
HPUX 1024MB
HPUX 1024MB
HPUX 1024MB
HPUX 1024MB
HPUX 1024MB

would create slices 2 to 8 each 1GB in size and after running idisk and insf the command
diskinfo /dev/rdsk/cXtYd0s5 would tell you that it is a disk of 1024MB in size.

Richard,

also with 11.23 the boot disk usually has a third "service" partition:
3
EFI 500MB
HPUX 100%
HPSP 400MB

check current boot disk and run diskinfo on the slices to align the partitioning of the mirrror disk.
