DLM Command Utilities
The commands utilized in the DLM utility set are:
cfallvpath
extendvg4vp
lsvpcfg
mkvg4vp
restvg4vp
savevg4vp
vp2hd
hd2vp
The utility "lsvpcfg" is most commonly used to see if redundant paths are available and LUN identifier information.
A sample output of the command:
vpath0 (Avail pv egate1vg) HI_R450294B0E67 = hdisk5 (Avail ) hdisk50 (Avail )
vpath1 (Avail pv egate1vg) HI_R450294B0E68 = hdisk6 (Avail ) hdisk51 (Avail )
vpath2 (Avail pv egate6vg) HI_R450294B0E69 = hdisk7 (Avail ) hdisk52 (Avail )
vpath3 (Avail pv egate104vg) HI_R450294B0E6E = hdisk8 (Avail ) hdisk53 (Avail )
vpath4 (Avail pv egate104vg) HI_R450294B0E6F = hdisk9 (Avail ) hdisk54 (Avail )
