Hello HP,
I need to add drives to vg01, but I have reached max_pv value of 18. Is there a way to extend this value ?

No, max PV is set upon vgcreate. This is why careful planning is important.

Hi Jerry:

You could try opening a case with HP. I believe that there is an unsupported utility that may be able to munge the LVM headers.

Otherwise, you will need to recreate the volume group from scratch, providing appropriate arguments for your immediate and future expectations. See the manpages for 'vgcreate'.

Recreate from scratch I'm afraid with the -p to set number of pv's:

vgcreate -s 64 -p 128
