What is an Access LUN on an E-Series System?

Applies to

E-Series SANtricity Software

Answer

  • The Access LUN (UTM LUN):
    • Is mapped by default
    • Only function is to allow in-band management
    • Allows SCSI commands to be translated to symbol commands for SANtricity management for SAN ports
  • I/O operations not supported on UTM LUNs
  • If storage is only managed by Out-of-Band Ethernet connections
    • Unmap the Access LUN
  • Linux OS will allow blacklisting of the UTM LUN in multipath.conf file
    • Example:

blacklist {
     device {
          vendor "*"
          product "Universal Xport"
     }
}
