Update the ‘ziorep_config’ utility to print FCP-LUN details when the ‘-M’ option is used. Now, ‘ziorep_config -M' option prints FCP LUN(fcp-lun) ID along with the existing FCP device bus-id and WWPN. This addition helps correlate the output with command 'multipathd -k', subcommand 'show topo' output, aiding in better visibility and mapping of FCP devices to their respective LUNs in multipath environments. $ ziorep_config -t -M adapter remote_port LUN scsi_dev multipath_device ======================================================================== 0.0.1967 0x500507630704572c 0x405240f500000000 /dev/sda /dev/mapper/mpatha 0.0.1967 0x500507630704572c 0x405340f500000000 /dev/sdb /dev/mapper/mpathb 0.0.1927 0x500507630700572c 0x405240f500000000 /dev/sdc /dev/mapper/mpatha 0.0.1967 0x500507630704572c 0x405440f500000000 /dev/sdd /dev/mapper/mpathc 0.0.1927 0x500507630700572c 0x405340f500000000 /dev/sde /dev/mapper/mpathb 0.0.1927 0x500507630700572c 0x405440f500000000 /dev/sdf /dev/mapper/mpathc 0.0.1967 0x500507630704572c 0x405540f500000000 /dev/sdg /dev/mapper/mpathd 0.0.1927 0x500507630700572c 0x405540f500000000 /dev/sdh /dev/mapper/mpathd The LUN IDs from the above output can be correlated with multipath's H-C-T-L(LUN ID in decimal) of each FCP devices as shown below, $ multipathd -k multipathd > show topo create: mpatha (36005076307ffd72c00000000000052f5) dm-0 IBM,2107900 size=40G features='1 queue_if_no_path' hwhandler='1 alua' wp=rw `-+- policy='service-time 0' prio=50 status=active |- 0:0:0:1089814610 sdc 8:32 active ready running `- 1:0:0:1089814610 sda 8:0 active ready running create: mpathb (36005076307ffd72c00000000000053f5) dm-1 IBM,2107900 size=40G features='1 queue_if_no_path' hwhandler='1 alua' wp=rw `-+- policy='service-time 0' prio=50 status=active |- 0:0:0:1089814611 sde 8:64 active ready running `- 1:0:0:1089814611 sdb 8:16 active ready running create: mpathc (36005076307ffd72c00000000000054f5) dm-4 IBM,2107900 size=20G features='1 queue_if_no_path' hwhandler='1 alua' wp=rw `-+- policy='service-time 0' prio=50 status=active |- 0:0:0:1089814612 sdf 8:80 active ready running `- 1:0:0:1089814612 sdd 8:48 active ready running create: mpathd (36005076307ffd72c00000000000055f5) dm-5 IBM,2107900 size=20G features='1 queue_if_no_path' hwhandler='1 alua' wp=rw `-+- policy='service-time 0' prio=50 status=active |- 0:0:0:1089814613 sdh 8:112 active ready running `- 1:0:0:1089814613 sdg 8:96 active ready running Signed-off-by: Ajaykumar Rajappa <ajaykr@linux.ibm.com> Reviewed-by: Chinmaya Kajagar <chinmayk@linux.ibm.com> Reviewed-by: Nihar Panda <niharp@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
