Solution 1643673.1 : Oracle ZFS Storage: Disks Not Showing or 4 Port Thebe-2 HBA Disappears after Cabling up Disk Trays

Applies to:

Sun ZFS Storage 7320 - Version All Versions to All Versions [Release All Releases]
Sun ZFS Storage 7420 - Version All Versions to All Versions [Release All Releases]
Oracle ZFS Storage ZS3-2 - Version All Versions to All Versions [Release All Releases]
Oracle ZFS Storage ZS3-4 - Version All Versions to All Versions [Release All Releases]
7000 Appliance OS (Fishworks)

Symptoms

After cable up of disk trays and power on of an array with the Thebe2 4-port SAS2 HBA, no disks are seen and the 4-port SAS2 Thebe2 HBA appears to be non-functional.

For a 'new' installation, the system may log this error prior to boot looping:

"failed to acquire SAS zone lock: SAS zone locking violation (lost)"

Cause

The high density HBA end of the disk tray to HBA cable is plugged in upside down into the Thebe2 HBA and this will cause the HBA to not function properly.

Even though this connector is keyed it can be with a little more force inserted upside down.

Solution

For the 7320 and ZS3-2 type installations where the HBA is installed horizontally, install the cables such that the blue pull tabs are on the bottom side of the connector -

Horiz-HBA

For the 7420 and ZS3-4 type installations where the HBA is installed vertically, install the cables such that the blue pull tabs are on the right side of the connector -

VERT-HBA
