I see some dead paths on running powerpath. None of these dead paths are in my /etc/lvmtab file. I am unable to clear them with "powermt check". (I am trying to avoid a reboot - but if that is the only way out then I will have to work on that.) Any inputs from your end to clear these paths without a reboot would be most appreciated.<BR /><BR />I ran these commands in this sequence:<BR /># ioscan -fn<BR /># insf<BR /># powermt config<BR /># powermt display dev=all<BR /><BR /># powermt remove force dev=c47t3d1<BR />Cannot remove device that is in use: c47t3d1<BR /># powermt remove force dev=c55t4d2<BR /># powermt remove force dev=c57t4d2<BR /><BR /><BR />(root):/etc:# powermt check<BR />Warning: Symmetrix device path c55t4d2 is currently dead.<BR />Do you want to remove it (y/n/a/q)? y<BR />Warning: Symmetrix device path c57t4d2 is currently dead.<BR />Do you want to remove it (y/n/a/q)? y<BR />Warning: CLARiiON device path c47t3d1 is currently dead.<BR />Do you want to remove it (y/n/a/q)? y<BR />Cannot remove device that is in use: c47t3d1<BR /> Thu, 03 Mar 2011 15:20:53 GMT Kennedy G.
