How to create a Striped Mirror logical volume

[RSA]

Wow!!! It's working.

The option must be activated:

export LVM_CONFIGURE=1; lvmadm -i LargeLVStripeMirror; krs_flush

Now everything is working:

lvcreate -L 90 -i 3 -I 64 -m 1 /dev/vg02

Warning: rounding up logical volume size to extent boundary at size "96" MB.

Logical volume "/dev/vg02/lvol1" has been successfully created with

Logical volume "/dev/vg02/lvol1" has been successfully extended.

Thanks to all

What I was thinking was something like this:

lvcreate -L 100 -i 2 -I 64 -m 1 -s g /dev/vg02

Your LV would hopefully be created as a stripe across 2 disks, hopefully in one PVG and then mirrored to the other PVG.

Hi (again) Ralph:

Very good! Where is the 'lvmadm' that you posted, documented? Did the response center offer this?

Regards!

Hi James.
Yes, the HP Support Center offered this additional information. It's not documented in the Patch description.

Hopefully HP will update the patch documentation and list that in the "Special Installation Instructions" (or whatever that section is) so it is known.

That is a major oversight on HP's part.

After applying the following commands:

export LVM_CONFIGURE=1; lvmadm -i LargeLVStripeMirror; krs_flush

the creation of Raid10 / Raid01 logical volumes is possible with HP-UX 11.23 and the mentioned patch.
