volumes already in the volume group. Clearly this checking only applies if the disks involved (those
already in the volume group and those being added) in the operation are EMC Symmetrix. Should the
command find an incompatibility, a message of the following type will be produced:
"Attempt to mix incompatible EMC Symmetrix disk types failed. Volume group contains standard
disks, but physical volume /dev/dsk/cxtxdx contains EMC BCV DISK. Please consult the EMC Sym-
metrix documentation, if applicable".
Cross-Cabinet Volume Group Warnings
On multi-cabinet V-Class systems, it is possible to create a volume group using physical volumes that are
physically attached to different cabinets. However, due to limitations in the HP-UX boot sequence, such a
cross-cabinet volume group cannot contain root, boot, swap, or dump logical volumes. If the volume group
vg_name contains a root, boot, swap, or dump logical volume, and by adding the physical volume(s)
specified by pv_path to the volume group it would become cross-cabinet, then vgextend will fail.
