When i would connect a hardisk suppose of 34 gb in voume group what it would be define as ?hdisk or pdisk
what is pdisk??/ is it partition in hardisve that is hdisk???
is the structure like this
Volume group ------
logical volume that is lv00
physical disk i.e hardisk hdisk0
physical partition pdisk???? what is physical volume group
i have two hdisk in server that is rootvg mirrored and then ssa array
hdisk 1 to hdisk 12
and pdisk showing size 34gb each???
