From c333f91d4cfded0f992fda7f52af273de68d6159 Mon Sep 17 00:00:00 2001 From: Ajaykumar Rajappa Date: Mon, 28 Jul 2025 08:33:29 +0200 Subject: [PATCH] ziomon/ziorep_config: Add fcp-lun to -M option output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Reviewed-by: Chinmaya Kajagar Reviewed-by: Nihar Panda Signed-off-by: Jan Höppner --- ziomon/ziorep_config | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/ziomon/ziorep_config b/ziomon/ziorep_config index cdfdf948..5a6a3493 100755 --- a/ziomon/ziorep_config +++ b/ziomon/ziorep_config @@ -303,6 +303,7 @@ sub mapper_report { my $adapters = shift; my $ports = shift; + my $luns = shift; my $s_devs = shift; my $m_devs = shift; my @out_str; @@ -312,18 +313,20 @@ sub mapper_report return; } if ($_[0]) { - print "adapter remote_port scsi_dev multipath_device\n", - "=====================================================\n"; + print "adapter remote_port LUN scsi_dev multipath_device\n", + "========================================================================\n"; } foreach my $hctl (sort keys %devices) { next if (!defined $devices{$hctl}{mp_dev}); next if (@$adapters && "@$adapters" !~ /\b$devices{$hctl}{hba_id}\b/); next if (@$ports && "@$ports" !~ /\b$devices{$hctl}{wwpn}\b/); + next if (@$luns && "@$luns" !~ /\b$devices{$hctl}{lun}\b/); next if (@$s_devs && "@$s_devs" !~ /\b$devices{$hctl}{dev}\b/); next if (@$m_devs && "@$m_devs" !~ /\b$mapper_dev{$devices{$hctl}{mp_dev_mm}}\b/); my @line_str; push @line_str, $devices{$hctl}{hba_id}; push @line_str, $devices{$hctl}{wwpn}; + push @line_str, $devices{$hctl}{lun}; push @line_str, "/dev/".$devices{$hctl}{dev}; push @line_str, "/dev/mapper/".$mapper_dev{$devices{$hctl}{mp_dev_mm}}; push @out_str, "@line_str\n"; @@ -510,6 +513,6 @@ if ($device_rep) { } if ($map_rep) { - mapper_report(\@adapter, \@port, \@s_dev, \@m_dev, $header); + mapper_report(\@adapter, \@port, \@lun, \@s_dev, \@m_dev, $header); }
