How to find HBA WWN via ESXi Shell / CLI

with thanks to http://www.vstrong.info

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:
  ?

  1 2	~ # ls /proc/scsi/  mptsas   qla2xxx

• Look for a folder like ‘qla2xxx‘ – QLogic HBA, ‘lpfc820‘ – Emulex HBA, ‘bnx2i” – Brocade HBA;
• Run ‘ls /proc/scsi/qla2xxx’. You will get a list of files, named by a number. Each file contains information about one HBA;
  ?

  1 2	~ # ls /proc/scsi/qla2xxx/ 6  7

• Now run ‘cat /proc/scsi/qla2xxx/6‘ to get full info on the HBA. Alternatively, run the following commands:
  • Run ” cat /proc/scsi/qla2xxx/6 | grep -A3 ‘SCSI Device Information:’  ” to get WWNN and WWPNs:
    ?

    1 2 3 4

    ~ # cat /proc/scsi/qla2xxx/6 | grep -A3 'SCSI Device Information:' SCSI Device Information: scsi-qla0-adapter-node=20000024ff31f0c8:000000:0; scsi-qla0-adapter-port=21000024ff31f0c8:000000:0;

  • Run “ cat /proc/scsi/qla2xxx/6 | grep ‘Host Device Name’ ” to get vmhba number:
    ?

    1 2	~ # cat /proc/scsi/qla2xxx/6 | grep 'Host Device Name' Host Device Name vmhba3

Add new rules in ESXi4:esxcli nmp satp addrule -s VMW_SATP_ALUA -V FALCON -M "IPSTOR DISK" -c tpgs_on
esxcli nmp satp setdefaultpsp --psp="VMW_PSP_RR" --satp="VMW_SATP_ALUA"
