Error Calling Out /sbin/mpath_prio_rdac
com> Subject: RE: [dm-devel] Multipathd not starting up properly Date: Wed, 30 Aug 2006 11:11:40 -0400 Hey Seth, Forewarning: While I've done multipathing for quite some time I am new to dm, so I'm going on multipathing / SCSI knowledge more than dm knowledge. It is possible I may be leading you down the wrong path (no pun intended). That being said, I have to assume that /sbin/mpath_prio_alua is issuing a report target ports groups (SCSI cmd) to determine ALUA priority. You may want to issue the "sg_rtpg" command to each of your paths and see if that is failing anywhere. That seems to be the rough equivalent of sending sg_inq when a path seems to be down. Usually path tests are done with inquiry and/or TUR. ALUA preference must be determined from report target port groups. That will at least tell you if it's something obvious like old firmware that doesn't support ALUA (how HP does their new A/A) or a check condition. -- not suggesting that's the problem, just giving an example -- FWIW, Brian -----Original Message----- From: dm-devel-bounces redhat com [mailto:dm-devel-bounces redhat com] On Behalf Of seth vidal Sent: Wednesday, August 30, 2006 8:25 AM To: device-mapper development Subject: Re: [dm-devel] Multipathd not starting up properly On Wed, 2006-08-30 at 09:42 +0200, Hannes Reinecke wrote: > Adam Huffman wrote: > > I'm seeing the following messages when I start multipathd: > > > > Aug 29 19:00:21 multipathd: error calling out /sbin/scsi_id -g -u -s > > /block/sda > > Aug 29 19:00:21 multipathd: error calling out /sbin/scsi_id -g -u -s > > /block/sdb > > > > Here is the output of multipath -v 3: > > > > > [ .. ] > > path checker = readsector0 (internal default) > > state = 2 > > getprio = (null) (internal default) > > prio = 1 > > getuid = /sbin/scsi_id -g -u -s /block/%n (internal default) > > error calling out /sbin/scsi_id -g -u -s /block/sda > > This is your problem.
