Description
For Pillar Axiom 600 Storage Systems, drive failures may be induced as a result of power removal from a single Brick power cooling unit in combination with certain disks and slots (as described below). A shutdown of the Axiom system prior to performing planned maintenance on the AC power is required.
Occurrence
This issue can occur on the following platform:
- Pillar Axiom 600 Storage System - All Versions and Releases
The following disks are affected, when installed in zero-based slots 3-8 and 12 (Hot Spare):
- 1450-00264-xx – 500GB 7200rpm SATA Disk Drive
- 1450-00265-xx – 500GB 7200rpm SATA 13th (spare) Disk Drive
- 1450-00266-xx – 1TB 7200rpm SATA Disk Drive
- 1450-00267-xx – 1TB 7200rpm SATA 13th (spare) Disk Drive
Symptoms
Pillar Axiom 600 Storage Systems (as listed above) may experience certain drive failures.
Workaround
To avoid this issue, shut down the Axiom system prior to performing planned maintenance on the AC power. This action is to negate the possibility of any drives failing during the planned power maintenance operation.
For additional options or information on planned power outages for Pillar Axiom 600 systems, contact Oracle Technical Support.

History
18-Sep-2014: Document released, status Resolved
In Bricks containing the drive types listed above, if a Power Cooling Unit is turned off or fails,
the speed of the cooling fans in its redundant power partner are increased to compensate. This in
turn increases the chassis vibration which can result in one or more drive failures. This increased
vibration may cause premature drive failures in zero-based slots 3-8 and 12 (Hot Spare).
Drive errors and/or failures can increase as a result of increased vibrations created by the Power Cooling
fans speeding up to compensate the loss of its redundant partner in the same Brick. The 500GB and 1TB drives
listed above are susceptible to these vibrations when installed in the middle 6 positions within a brick.
The compatible 2TB drive is not susceptible to the increased fan vibrations.
