Chapter 5 Troubleshooting Your Array
Troubleshooting Array Startup Failure
If your system halts during startup, check the array's front panel indicators. See
.
There are a few reasons that an array could be denied power ON. In this case, the “Power On Enclosure” option
in the CMC GUI should be used to power on the array once the reason has been addressed.
Be sure to check for:
•
Fabric Mismatch—If the array is configured for a fabric that does not have a 10 Gb –KR IOM installed.
•
Not enough power available—more or higher-wattage power supplies are needed
•
110 V AC—If power supplies in the enclosure support 110 V AC, when the enclosure is powered on, the
array will not power on right away like other blades and IOMs. A Power On Enclosure action is needed.
Troubleshooting Loss of Communication
For information about troubleshooting loss of communication, see
Array Networking Considerations on page 6
Troubleshooting Array Connections
The PS-M4110 is connected to the M1000e enclosure by internal connections between the array and the
enclosure. There are no cable connections that you can check for problems, but you can:
•
Confirm that the PS-M4110 blade array is properly seated within the M1000e enclosure.
•
Confirm that the array's control modules and drives are properly seated within the PS-M4110 array drawer.
Troubleshooting External Connections
The PS-M4110 does not have direct external connections that you can troubleshoot. The PS-M4110 is connected
to power, Ethernet, and other devices through its internal connections to the M1000e enclosure.
However, you can check or confirm:
•
If Pass-Through IOMs are in use, verify that all four network ports connecting the PS-M4110 are cabled into
the SAN network.
•
If Switch IOMs are in use, verify that the IOM switches are connected to the SAN network, and that the
four internal ports connecting to the PS-M4110 are allocated to the SAN network.
