Hard disk drive problems - IBM NeXtScale nx360 M4 Compute Node

Table 1. Hard disk drive symptoms and actions.
The hard disk drive's symptoms and actions table with one level of row and column headers.
Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. If an action step is preceded by "(Trained technician only)", that step must be performed only by a trained technician. Go to the IBM support website at the IBM support portal to check for technical information, hints, tips, and new device drivers or to submit a request for information.
Symptom	Action
Not all drives are recognized by the hard disk drive diagnostic tests.	Remove the drive that is indicated by the diagnostic tests; then, run the hard disk drive diagnostic tests again. If the remaining drives are recognized, replace the drive that you removed with a new one.
The server stops responding during the hard disk drive diagnostic test.	Remove the hard disk drive that was being tested when the server stopped responding, and run the diagnostic test again. If the hard disk drive diagnostic test runs successfully, replace the drive that you removed with a new one.
A hard disk drive was not detected while the operating system was being started.	Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic tests again.
A hard disk drive passes the diagnostic Fixed Disk Test, but the problem remains.	Run the diagnostic SCSI Fixed Disk Test (see Running DSA Preboot diagnostic programs). Note: This test is not available on servers that have RAID arrays or servers that have SATA hard disk drives.
