How do I find my HBA wwn number in Linux?
Here is a solution to find WWN number of HBA and scan the FC Luns.
- Identify the number of HBA adapters. systool -c fc_host -v.
- To get the WWNN (World Wide Node Number) of HBA or FC card in Linux.
- To get the WWPN (World Wide Port Number) of HBA or FC card in Linux.
- Scan newly added disks or rescan existing LUNs in Linux.
How do I get HBA wwn?
Step 1 Run the fcinfo hba-port command to the HBA WWN in Solaris 10. Manufacturer: QLogic Corp. Manufacturer: QLogic Corp. Step 2 Run the prtpicl -v -c scsi-fcp |grep -i wwn command to view the HBA WWN in Solaris 8 and 9.
How do I find WWPN number in Linux?
To locate the WWPN without restarting the host, you can use any of the following methods: For QLogic or Emulex adapters, you can find the WWPN in the /proc/scsi/ adapter_type / n directory, where adapter_type is the host adapter type and n is the host adapter number for your card.
What is HBA in Linux?
Fibre Channel (FC) Host Bus Adapters(HBA) are interface cards that connects the host system to a fibre channel network or devices. The two major manufacturers of FC HBAs are QLogic and Emulex and the drivers for many HBAs are distributed in-box with the Operating Systems.
How do I find my WWN virtual machine number?
Alternatively, run the following commands:
- Run ” cat /proc/scsi/qla2xxx/6 | grep -A3 ‘SCSI Device Information:’ ” to get WWNN and WWPNs: ~ # cat /proc/scsi/qla2xxx/6 | grep -A3 ‘SCSI Device Information:’
- Run ” cat /proc/scsi/qla2xxx/6 | grep ‘Host Device Name’ ” to get vmhba number:
How do I find the LUN ID in Linux?
For each additional logical unit number (LUN) that needs to be discovered by the Linux kernel, perform the following steps: At the command prompt type echo “scsi-add-single-device H C I L” >/proc/scsi/scsi where H is the host adapter, C is the channel, I id the ID and L is the LUN and press the key.
Where is HBA WWN number ESXi server?
2. How to find HBA WWN via ESXi Shell / CLI:
- Connect to ESXi shell either via putty/SSH or DCUI (Direct Console User Interface) / server console.
- Run ‘ls /proc/scsi/’ and check the folder names:
- Look for a folder like ‘qla2xxx’ – QLogic HBA, ‘lpfc820’ – Emulex HBA, ‘bnx2i” – Brocade HBA;
- Run ‘ls /proc/scsi/qla2xxx’.
How do I find the Wwid of a device in Linux?
You can get the WWID by running the scsi_id command on a device. For example, assume that /dev/sda is a local SCSI drive. To obtain the WWID on systems running Red Hat Enterprise Linux 7 or 6 series or SUSE Linux Enterprise Server 12 and 11, enter /lib/udev/scsi_id -gud /dev/ sda .
How do I find my LUN ID?
Using Disk Manager
- Access Disk Manager under “Computer Management” in “Server Manager” or in the command prompt with diskmgmt.msc.
- Right-Click on the side-bar of the disk you wich to view and select “Properties”
- You will see the LUN number and the target name. In this example it’s “LUN 3” and “PURE FlashArray”
