MirrorUX and EFI partition

[AndreR_1]

How to mirror a disk with an EFI partition using MirrorUX ?

HP-UX = B11.22 on ia64

MirrorUX works fine but it does not include the EFI partition, which it it needs to boot.

Mirror/UX is a LVM utility. Refer to VXVM and mirroring. Try vxassit.

Meant vxrootmir:

/etc/vx/bin/vxrootmir ???v ???b ???R c5t2d1

Which requires ADVANCED vxvm to mirror.

[AndreR_1]

As far as I know vxrootmir or rootability is only supported with VxVM 3.5.
I have VxVM 3.1....

Probably there is a difference between the Veritas version and the HP version of Volume Manager in the feature availability.

Still having the question what does VxVM do with the EFI partition on the disk ?

[Michael Steele_2]

First, you need a version of vxvm that supports mirroring: 3.2 or 3.5.

Second, you use the mkboot command with Advanced VXVM to enable the EFI:

/usr/sbin/mkboot -e [-l] [-s efi_file_path] [-v] [-W] device

-e Use IA-64 EFI layout. This option causes mkboot to copy EFI utilities from /usr/lib/efi to the EFI partition on the disk; see idisk(1m) and efi(4). This option is applicable only on IA-64 machines; it may not be used on PA. (Use the -s option to specify a non-default source for EFI files.)

Here is a link to the man page:

You'll also need the idisk command:

And here is a terse discussion about efi and its FAT file system origins:
