Error Calling Out Sda
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.

Am i missing something? It doesn't make sense that only sdb and sdc would be blocked but not sda which has the OVS installed on it? My multipath.conf is shown above and I do not error calling out see where sd* devices are being blocked. I am new to the whole multipath thing, what is a "legit path_checker" and what would I change in the multipath.conf file?sda is blacklisted as well, but that's by design, as we always blacklist the install disk. We're now trying to work out why it's also blacklisting the sdb and sdc devices. Can you start multipath manually: # service multipathd start Like Show 0 Likes(0) Actions 16. Re: oracle vm 3.0.2 - doesn't recognize my local storage for a repository jepva Dec 7, 2011 6:26 PM (in response to Avi Miller-Oracle) Ok, so even after starting it manually it wasn't working, but after some research I found this is the way to start multipath: [root@dabney ~]# service multipathd start Starting multipathd daemon: [root@dabney ~]# modprobe dm-multipathAfter issuing the modprobe command the multipath commands start working, Multipath -ll still doesn't show anything, and nothing else appears under /dev/mapper, but issuing multipath -v3 shows this: Dec 07 13:25:21 | sdb: not found in pathvec Dec 07 13:25:21 | sdb: mask = 0x1f Dec 07 13:25:21 | sdb: dev_t = 8:16 Dec 07 13:25:21 | sdb: size = 229236
