Applies to

  • SAN
  • Linux
  • WWID(The World Wide Identifier)

Description

  • The World Wide Identifier (WWID) can be used in reliably identifying disk devices in Linux OS.
  • It is a persistent, system-independent ID that the SCSI Standard requires from all SCSI devices.
  • The WWID identifier is guaranteed to be unique for every storage device, and independent of the path that is used to access the device.
  • The WWID number can be used to determine a LUN's serial number and vice versa
