Table 8. Storage device problems and service actions (continued)
Problem Service action
More than one storage device suddenly stops working
1. If the system was recently installed, moved, serviced,
or upgraded, verify that the device is seated and
installed properly.
2. Check the system logs to verify whether the system
detected a problem.
3. If the devices are connected to a RAID adapter,
replace the RAID adapter.
4. If the devices are small form factor NVMe drives,
replace the following items one at a time until the
problem is resolved:
v
NVMe host bus adapter
v Cables
v Disk drive backplane
v Small form factor NVMe drives
5. Replace the cable that connects the disk drive
backplane to the RAID adapter. If the system does
not have a RAID adapter, replace the cable that
connects the disk drive backplane to the system
backplane.
One storage device suddenly stops working
1. Verify that all internal cables are properly seated and
are not physically damaged.
2. Check the system logs to verify whether the system
detected a problem.
3.
Replace the drive.
4. Replace the system backplane.
5. Replace the cable.
6. If you have a RAID adapter that is installed, replace
it.
Other problems Check the messages and resolve any other problems that
were detected. Then, test the drive again. If the drive
continues not to function, refer to the documentation for
the drive.
Identifying the location of the PCIe adapter by using the slot number
The error message provides information to help you to determine the location of the PCIe adapter.
For example, the log might contain an error similar to the following text:
[131779.752714] EEH: PHB#0 failure detected, location: WIO Slot1
Use the following table to map the slot number information in the operating system log to the PCIe
adapter description and service action.
