Fibrechannel Analyse

Kommandos : Solaris

luxadm

luxadm -e port

Gibt die Hardwarepfade der vorhandened Fibrechannelports und deren Status aus: <syntaxhighlight lang=bash>

  1. luxadm -e port

/devices/pci@79,0/pci10de,378@b/pci1077,143@0/fp@0,0:devctl CONNECTED /devices/pci@79,0/pci10de,378@b/pci1077,143@0,1/fp@0,0:devctl NOT CONNECTED /devices/pci@79,0/pci10de,376@e/pci1077,143@0/fp@0,0:devctl CONNECTED /devices/pci@79,0/pci10de,376@e/pci1077,143@0,1/fp@0,0:devctl NOT CONNECTED </source> 

2 Dualport Karten:
/devices/pci@79,0/pci10de,378@b/pci1077,143@0 und ...,1
/devices/pci@79,0/pci10de,376@e/pci1077,143@0 und ...,1

<syntaxhighlight lang=bash>

  1. prtdiag -v | head -1

System Configuration: Sun Microsystems Sun Fire X4440 </source>

Aus der Seite Sun x86 Platforms: Matrix of Recognized Device Paths (Doc ID 1277396.1) (Oracle Support Login benötigt): 

Sun Fire x4440 (Tucana)
PCI:
PCIe SLOT0         /pci@0,0/pci10de,375@f/pci1000,3150@0 // with PCI Express 8-Port SAS/SATA HBA
PCIe SLOT0         /pci@0,0/pci10de,375@f/               // without PCI Express 8-Port SAS/SATA HBA
PCIe SLOT1         /pci@0,0/pci10de,376@e/
PCIe SLOT2         /pci@7c,0/pci10de,377@f/
PCIe SLOT3         /pci@0,0/pci10de,377@a/
PCIe SLOT4         /pci@7c,0/pci10de,376@e/
PCIe SLOT5         /pci@7c,0/pci10de,378@b/
(7c can be renamed something else depending on BIOS/OS version)

Also stecken unsere Karten in Slot 4 und 5.

luxadm -e dump_map <HW_path>

Gibt die Tabelle der bekannten Geräte an einem Port aus <syntaxhighlight lang=bash>

  1. luxadm -e dump_map /devices/pci@79,0/pci10de,378@b/pci1077,143@0/fp@0,0:devctl

  • Port_ID <Switch_ID><Switchport><??>
Es sind also offensichtlich 2 Switches in der Fabric an Port /devices/pci@79,0/pci10de,378@b/pci1077,143@0/fp@0,0:devctl
und zwar mit der ID 1 und mit der ID 3.
Switch ID 1
 Port 1 und  5 : Node WWN 200400a0b85bb030
 Port 2 und 14 : Node WWN 200600a0b86e103c
 Port 8        : Node WWN 2000001b32902d45 (Wir selbst)
Switch ID 3
 Port 1 und  5 : Node WWN 200200a0b85aeb2d
 Port 2 und  6 : Node WWN 200600a0b86e10e4 

Wir hängen also mit 2 Storages auf dem Switch mit der ID 1 und haben eine Verbindung zu einem Switch mit der ID 3 an dem 2 weitere Storages hängen.
  • Node WWN
Wir sehen hier 4 Disk Devices mit jeweils 2 Einträgen (Gleiche Node WWN)
  • Port WWN
Dies ist die Port WWN der an den Switch angeschlossenen Geräte (unter 8 finden wir uns selbst).
Pro Storage sehen wir hier 2 Port WWNs, also 2 Pfade über unseren einen Hostport.

Daher nachher 4 Pfade (2 Pro Hostport) beim #mpathadm list lu.

  • Type
Disk Device: Storage
Host Bus Adapter: FC-Karte

  • Vendor: SUN
Hersteller
  • Product ID: STK6580_6780
Also ein StorageTek 6580/6780
  • Revision: 0784
Grobe Firmwarepeilung (Firmware Version: 07.84.47.10)

Siehe hier #lsscs list array <array_name>

  • Serial Num: SP01068442
Praktisch, wenn man mit NetApps arbeitet, um die LUNs zuzuordnen.
  • Unformatted capacity: 204800.000 MBytes
Immer gut zu wissen
  • Write Cache: Enabled
Die Batterie im Storage sollte also OK sein ;-)

Zuweisung Controller zum FC-Port über: <syntaxhighlight lang=bash>

  1. ls -al /dev/cfg/c6

lrwxrwxrwx 1 root root 60 Sep 3 2009 /dev/cfg/c6 -> ../../devices/pci@79,0/pci10de,376@e/pci1077,143@0/fp@0,0:fc </source> Man sieht den Hardwarepfad von #luxadm -e port

Class: 

Via ALUA (Asymmetric Logical Unit Access) teilt das Device dem Host mit, über welche Pfade der Host primär auf die LUN zugreifen soll.

  1. Dies ist der "Principal" (alle andere sind "Subordinate") der Fabric "Fabric1" (switchRole:, zoning:)
  2. Der Switch ist gezoned (zoning:)
  3. SwitchID ist "fffc01"
  4. Es ist ein 24-Port Switch
  5. Es gibt einen doppelten ISL (InterSwitchLink) zu einem anderen Switch E-Port (san-sw_21)
  6. 6 Ports sind mit SFPs bestückt, aber nicht belegt (0,4,11-15)
  7. 8 Ports haben keine Lizenz und auch kein SFP (No_Module)
  8. 9 Ports sind belegt

fcp config <port> : Welche WWN habe ich?

<syntaxhighlight lang=bash> fas01> fcp config 1a 1a: ONLINE <ADAPTER UP> PTP Fabric 

       host address 010600
       portname 50:0a:09:83:90:00:29:24  nodename 50:0a:09:80:80:00:29:24
       mediatype auto speed auto

</source> Kleines Schmankerl ist noch die "host address", die uns zeigt, daß wir auf Switch-ID 01 Port 06 hängen.

sanlun lun show -d <dev> (mit Solaris und ZPool)

Wenn man wissen möchte, welche NetApp LUNs zu einem ZPool gehören, geht das folgender Maßen:

<syntaxhighlight lang=bash>

  1. zpool status | nawk '/c[0-9]t/{dev=$1;gsub(/s[0-9]+$/,"",$1);command="/opt/NTAP/SANToolkit/bin/sanlun lun show -d /dev/rdsk/"$1"s2";command | getline; command | getline; print dev,$1$2;next;}{print;}'

</source> Beispiel: <syntaxhighlight lang=bash>

  1. zpool status | nawk '/c[0-9]t/{dev=$1;gsub(/s[0-9]+$/,"",$1);command="/opt/NTAP/SANToolkit/bin/sanlun lun show -d /dev/rdsk/"$1"s2";command | getline; command | getline; print dev,$1$2;next;}{print;}'
