Re: vg00 construction.

Hi Fizan,

man vgcreate is the answer ;)
here is are the steps to create a VG with the same parameters:

# mkdir /dev/VGNAME
# mknod /dev/VGNAME/group c 64 0xFREE_MINOR
# vgcreate -e 4355 -l 255 -p 16 -s 32 VGNAME DEVICES

where:
VGNAME is the name of your VG
FREE_MINOR is a free minor number for major 64 -> do an 'll /dev/*/group | sort -k6' and choose a free minor number for your new VG
DEVICES -> here you should provide all the devices that were pvcreate'd before. keep in mind that a new disk must be initialized with pvcreate to for use with LVM

Re: vg00 construction.

Hi

root VG construction/reconstruction.

root VG vg00 is constructed at the time of a new-install,

the parameter that is -s thatis PE_Size once set cannot be changed without destroying and rcreatting that VG.

Other parameters that is MAx_PE_per_PV that is -p , MAX_LV that is -l, MAX_PV that is -p can be changed using the vgmodify command if that is 11.23 and vgmodify patches are there but that needs teh VG to be deactivated and in case you are having these and wish to perfoem on Root VG , you need to be in LVMMintennanace Mode that is -lm option of boot vmunix on IA or hpux -lm on PARISC.

also the lvol1. lvol2 and lvol3 are contiguous so those cannot be extended like other LVs that is using lvextend, so preferred Way as well as Reliable is IGnite backup and restore where at the ignite install you can reconfigure ypur root VG then extend miroorrs.
