How to find the OUI in a World Wide Node Name (WWNN) or World Wide Port Name (WWPN)
Each Fibre Channel node or networking device will have one and only one WWNN that uniquely identifies it. Each of these devices will have at least one and frequently very large numbers of ports (in the case of a switch for instance). Each of these ports is uniquely identifiable by its WWPN which is created based on the WWNN, so that any device will have one WWNN but could have many related WWPNs. The Fibre Channel naming format can take one of several forms. In general, the first nibble (4bits or 1/2 byte identifies the type of WWN. The second section depends on the type of WWN:
1. IEEE Name (NAA-1) The first nibble is a 1. The the next nibble and byte will equal 0:00. For example, 10:00:XX.XX.XX.VV.VV.VV, where the X represents OUI and the V indicates vendor assigned bytes).
IEEE name (NAA-1) – 10:00:00:00:c9:55:23:6b >00:00:c9<<<<<< OUI
2. IEEE Extended name (NAA-2) – The first nibble is a 2. The next 12 bits (1 nibble + 1 Byte) is vendor assigned, and is frequently used to identify port number on a multiport node. For example, 2P:PP:XX:XX:XX:VV:VV:VV (P is vendor assigned possibly a port ID, X is OUI, and V is vendor assigned)
IEEE Extended name (NAA-2) – 20:00:00:e0:8b:05:05:04 >00:e0:8b<<<<<<< OUI
3. IEEE Registered name (NAA-3) – The first nibble is a 2. The next three bytes are the OUI with the next 4 1/2 bytes are vendor assigned, frequently being the serial number with the last three nibbles being used for port identification. For example, 5X:XX:XX:XV:VV:VV:Vv:vv (where X is OUI, and V is vendor assigned might be serial number and v port ID)
IEEE Registered name (NAA-3) – 50:0a:09:81:87:39:45:3b >0:0a:09:8<<<<<<<<<<<OUI
Various Activities in IBM DS Storage
DS 5300, DS 5100, DS 4800 & DS 4700.
How to map a system to be a management station?
- You can delete host environment
- Create a new storage subsystem.
- Out-of-band management:
A storage node address is required.
A node can be a computer or some other device, such as a printer. Every node has a unique network address.
Your host IP address. Click No.
New host environment output:
How to define host? (Not the management station but production host)
How to create partitions (Luns)?
How to create an array (Raid Groups)?
How to map logical drives to host?
In computer hardware, a host controller, host adapter, or host bus adapter (HBA) connects a host system (the computer) to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI,Fibre Channel and eSATA devices.
Specify Host Type.
- Host Group Question (Define Host): Choose NO
- On Preview (Define Host) Click Save as Script then Click Finish
Setting up IBM Storage
- Verify FC “Devmgmt.msc (Device Manager)
- Launch the Console. (Example QConvergenceConsole.)
- Ping, Beacon & Serial etc
- WWPN World Wide Port Name (HBA)
- If iSCi you need to verify on server isci iniator and locate the target (Storage).
- From IBM DS Storage Manger > Subsystem
- Create Array and luns.
- Host and map logical drive to the host.
- Always verify the Host Type and HBA (WWPN)
- Same as Directly attached config.
- But you need to create a zoning on SAN Switch.
On SAN Switch
#aliascreate “Server1”, “HBA(WWPN)”
#aliascreate “DSstorage1”, “HBA(WWPN)”
#zonecreate “ZONECONF”, “Server1(Alias)”
#zoneadd “ZONECONF”, “DSstorage1 (Alias)”
- Create a config or just add to the zone to existing config.
#cfgcreate “RUNING”, “ZONECONF”
NOTE: VERIFY alias show or configshow and Effective configuration.
Creating Hot Spare
- Click the replace HDD on manger then go to advanced revive
Manual setup of HotSpare
- Click the hostspare or drive then Replace Drives.
According to IBM if you gonna replace HDD, After Pulling out the old HDD you should wait 30 to 60 sec. before you insert the new HDD.
