  • NetApp E-Series with:
    • DE460C 60-Drive Tray (SATA/SAS)
    • DE6600 60-Drive Tray (SAS)

Issue

  • The recovery-guru-procedures shows "Failure Entry: NO_REDUNDANCY_DRIVE-Recovery Failure Type Code: 32" on all 12 disk drives of the affected Drawer.  
  • In the ASUP STORAGE-ARRAY-PROFILE Section the DRIVES summary output shows all 12 disk drives in the same drawer in a Loss of redundancy status.

E-series all 12 disk drives are Loss of redundancy status in one Drawer

  • Also in the STORAGE-ARRAY-PROFILE Section, review the DRIVE CHANNELS subsection. In the example below we can see all of the drives in Tray 1 Drawer 4 are using the same preferred channel, and none of the drives have a redundant channel (path).
