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.

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 ;-)

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

Was sagt uns das?

  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

Backup der Switchconfig per Script

Put the backup host ssh-pub-key on the switches

fcsw1:root> cat >/root/.ssh/authorized_keys <<EOF
> ssh-dss AAAAB3NzaC1...
...
...
lF8qsgtTD8cc= root@host
> EOF

Generate ssh-key on the switches

fcsw1:root> ssh-keygen  
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
2a:23:33:...:69:bc:25:a5:f9 root@fcsw1
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
| ...             |
|                 |
+-----------------+

Copy the key to your backup users ~/.ssh/authorized_keys on backup host

fcsw1:root> cat /root/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAA...
...
KHnw1T1NaQ== root@fcsw1

Now the script on the backup host

# cat /opt/bin/backup_brocade_config

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