Four new hot-swappable SAS 300GB (assembly # 652564-B21) drives (drive p/n HGST HUC101830CSS200) were installed and configured as SAS Array B and built as RAID 5 .
After 5 days, one of the drives, bay 6, failed. Two replacement assemblies (one for a spare), same part number, were ordered (it was a refurb), but both failed after a couple of seconds. Rebooting the server did not help.
Tried original failed hard drive and began to rebuild, this process ran for 3 days and failed. Figured that since it started to rebuild, the bay was good, but not completely sure, could be bas refurbs.
Ordered two new drive assemblies, same part number, and received SAS 300GB (drive p/n HP EG0300FCVBF), the first one also failed after a couple of seconds.
Both drives, the HGST and HP, appear as data type, 300.0 GB, SAS, PHY count 2, 10.5k speed, transfer speed shown as PHY 1: 6 Gbps, PHY 2: Unknown.
What can be done?
