** Description changed: + [Impact] + Users of multipath will see incomplete output for the vendor and model values for devices where the first path is the path that is failed. + + [Test Cases] + 1) Experience a failed path: + echo 1 > /sys/devices/<path to device>/delete + (the above is an example for forcibly removing a path for SCSI via the /sys filesystem) + 2) run: sudo multipath -ll + 3) Verify the output, see below. + + Storage name (vendor and model usually) should always be displayed after + dm-* on the header line for a multipath device. + + [Regression Potential] + This is limited to output and is thus purely a cosmetic fix. Possible issues leading from that fix would include crashes due to an incorrect patch or the output for vendor/model info for the device to still be incorrect. + + ---- == Comment: #0 - Yueh Chyong Jackson <[email protected]> - 2015-01-27 16:54:58 == ---Problem Description--- power kvm client ubuntu ilp1fc85apA4 after error injection test (SVC node reboot), the multipath output show one path with #:#:#:# and did not show the storage name: mpath6 (3600507680284066f1800000000000172) dm-6 , <---------(missing storage name) size=3.0G features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=50 status=active | |- #:#:#:# - #:# failed faulty running <---------------------------------------- | `- 4:0:7:0 sdbr 68:80 active ready running `-+- policy='round-robin 0' prio=10 status=enabled - |- 4:0:9:0 sdbq 68:64 active ready running - `- 3:0:7:0 sdby 68:192 active ready running + |- 4:0:9:0 sdbq 68:64 active ready running + `- 3:0:7:0 sdby 68:192 active ready running this is a storage IBM svc storage + ---uname output--- + power kvm server: [root@ilp1fc85a ~]# uname -a Linux ilp1fc85a.tuc.stglabs.ibm.com 3.10.42-2018.1.pkvm2_1_1.46.ppc64 #1 SMP Fri Oct 17 10:41:35 CDT 2014 ppc64 ppc64 ppc64 GNU/Linux, + client uname : root@ilp1fc85apA4:~# uname -a Linux ilp1fc85apA4.tuc.stglabs.ibm.com 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:09:21 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux - - ---uname output--- - power kvm server: [root@ilp1fc85a ~]# uname -a Linux ilp1fc85a.tuc.stglabs.ibm.com 3.10.42-2018.1.pkvm2_1_1.46.ppc64 #1 SMP Fri Oct 17 10:41:35 CDT 2014 ppc64 ppc64 ppc64 GNU/Linux, - client uname : root@ilp1fc85apA4:~# uname -a Linux ilp1fc85apA4.tuc.stglabs.ibm.com 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:09:21 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux - ---Additional Hardware Info--- 4 adapters, coho, bluefin, houston,houston FCoE, with following storages: DS8800,TMS, xiv gen2, svc V7k ,texan, texan FCoE, client lun that use for running tests(data lun) are passthrough access to machines: power kvm server: ilp1fc85a 9.11.56.126 (ssh root/B!gm0ney) client: ilp1fc85apA4 9.11.56.72 (ssh root/B!gmoney) - the logs are save at: + the logs are save at: ip: 9.11.56.167(root/teamw0rk), under file: /root/bflocal/CYCLE18/CheckHostStatus_V2/CYCLE18_226/scripts/9.11.56.72.hostcheck.CHS.svc_nr.stop.20150127073959 ip: 9.11.56.168 (root/teamw0rk), under file: /PACKAGE/errlogs/Cycle18/SVC_NR/20150127081651/ c_85_g.ilp1fc85apA4.SVC_NR.Cycle18.27Jan15.081758.tar.gz - - - Machine Type = IBM Power System S824, product: 8286-42A,serial: 10CD74T - + Machine Type = IBM Power System S824, product: 8286-42A,serial: 10CD74T + ---Debugger--- A debugger is not configured - - Contact Information = ida jackson/[email protected], [email protected] - + + Contact Information = ida jackson/[email protected], [email protected] + Stack trace output: - no - + no + Oops output: - no - + no + System Dump Info: - The system is not configured to capture a system dump. - - *Additional Instructions for ida jackson/[email protected], [email protected]: + The system is not configured to capture a system dump. + + *Additional Instructions for ida jackson/[email protected], [email protected]: -Post a private note with access information to the mach - ine that the bug is occuring on. + ine that the bug is occuring on. -Attach sysctl -a output output to the bug. please let me know if other info is needed. thanks for looking into the problem == Comment: #9 - Vaishnavi Bhat <[email protected]> - 2015-02-11 04:11:40 == - == Comment: #17 - Andrea M.
