Description yizeng 2010-05-04 02:46:25 UTC
Description of problem:
a QLA2462 HBA with two ports attached to IBM SVC via brocade swith,when disabling one port of the swith,one path became fail, after enabling this port,the path can't recovery, in /var/log/mesage, always print 
multipathd: error calling out /sbin/mpath_prio_alua /dev/sdt

Version-Release number of selected component (if applicable):
2.6.9-67.EL #1 SMP Wed Nov 7 13:43:35 EST 2007 ia64 ia64 ia64 GNU/Linux

# rpm -qa | grep mapper

How reproducible:

Steps to Reproduce:
1.disable one port of switch attach to the IBM SVC
2.the path is fail
3.enable this port 
Actual results:
#multipath -l path14
path14 (360050768018082ddc00000000000098c)
[size=1 GB][features="1 queue_if_no_path"][hwhandler="0"]
\_ round-robin 0 [enabled]
 \_ 3:0:0:1  sdt  65:48  [failed][faulty]
\_ round-robin 0 [enabled]
 \_ 2:0:0:1  sdc  8:32   [active]

one path of LUN  failed and after enable the port with this path, path can't recovery. but the other paths is ok, for example :
path1 (360050768018082ddc000000000000993)
[size=1 GB][features="1 queue_if_no_path"][hwhandler="0"]
\_ round-robin 0 [enabled]
 \_ 2:0:0:8  sdj  8:144  [active]
\_ round-robin 0 [enabled]
 \_ 3:0:0:8  sdaa 65:160 [active]

Expected results:
all paths recovery correctly after the port enabled.

Additional info:
in /var/log/message, always print 

 kernel: device-mapper: dm-multipath: Failing path 65:144.
May  3 09:30:56 archprx26k46328 kernel: end_request: I/O error, dev sdz, sector 996112
May  3 09:30:56 archprx26k46328 multipathd: 65:144: mark as failed
May  3 09:30:56 archprx26k46328 multipathd: path3: remaining active paths: 1

actually the two paths are OK

Hi, I've got a similar behavior on 4.8.

Linux b25lciapp48.con.can.ibm.com 2.6.9-89.ELlargesmp #1 SMP Mon Apr 20 10:43:12 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

Red Hat Enterprise Linux AS release 4 (Nahant Update 8)



We've been seeing messages like this for quite a while:

multipathd: error calling out /sbin/mpath_prio_alua /dev/sdj

Unfortunately it took a while to discover this problem w/ the machine and we lost the early entries.
