HP-UX Reference (11i v2 07/12) - 1M System Administration Commands N-Z (vol 4)

vgreduce(1M) vgreduce(1M)

lvmtab ﬁle. Currently the max limit is 8 paths to a PV (seven alternates and one

primary). In this situation invoking the command without the

-f option will not

resolve the condition because the path is not attached to the volume group. Similarly

the condition would not be overcome by invoking with the

-f option as this works on

PVs rather than links.

pv_path The block device path name of a physical volume.

vg_name The path name of the volume group.
