luxadm

luxadm -e port

Gibt die Hardwarepfade der vorhandened Fibrechannelports und deren Status aus: 

# 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

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

# prtdiag -v | head -1
System Configuration: Sun Microsystems     Sun Fire X4440

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

Erklärung der interessanten Spalten:

  • 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.

  • 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 ;-)
