Error message: Striped mirrors are not supported

[L van Mourik]

Running HP-UX 11.23. Trying to setup striping & mirroring. Used the following commands:
lvcreate -i 4 -I 64 -n lvoradata1 /dev/vg01
lvextend -l 10 /dev/vg01/lvoradata1 \
/dev/dsk/c6t4d0 /dev/dsk/c6t5d0 \
/dev/dsk/c7t8d0 /dev/dsk/c7t9d0
lvextend -m 1 /dev/vg01/lvoradata1 \
/dev/dsk/c5t4d0 /dev/dsk/c5t5d0 \
/dev/dsk/c9t8d0 /dev/dsk/c9t9d0
After this xcommand the following error message appears: Striped mirrors are not supported. To enable mirroring options (-m, -M, -c),
do not specify the striping options (-i, -I) when creating logical volumes.

According to the HP-UX documentation striped mirrors are supported ?!?!

I am just going to state the obvious here:

> lvcreate -i 4 -I 64 -n lvoradata1 /dev/vg01

> To enable mirroring options (-m, -M, -c),
do not specify the striping options (-i, -I) when creating logical volumes.

I am going with the -i.

Oh and I will also choose the -I, even though it display as a lowercase l (el).

"According to the HP-UX documentation striped mirrors are supported ?!?! "

Where did you read this?

See this documentation:

"The following feature is new with the HP-UX 11i v3 release of MirrorDisk/UX:

Striped Mirrors: In previous releases, LVM supported a limited extent-based striped mirror functionality, as described in the lvcreate(1M) manpage..."

http://docs.hp.com/en/5991-7518/ar01s03.html

and

"Striped Mirrors: Releases prior to HP-UX 11i v3 only support extent-based striping via the -D option to lvcreate..."

http://docs.hp.com/en/5991-7518/ar01s06.html

Hi Torsten,

I read a lot of documents but can't remember which document described mirrored stripes. I'm sure it was documentation based on a HP-UX release prior to HP-UX 11.31.
Nevertheless, I followed your advise and used the -D option.

Thank you
Leo
