Installation Troubleshooting
This chapter explains what to do if you detect problems during the installation
of the SF7x storage enclosure.
The procedures in this chapter involve taking devices on- and off-line. This
causes a failure in the communications with the devices affected, resulting in
potential user problems. For this reason, the system manager should perform
an orderly shutdown of all DSSI integrated storage elements (ISEs) before any
troubleshooting. Refer to the service or maintenance manuals for the device.
8.1 Troubleshooting the SF7x Storage Enclosure
This section presents symptoms of a failed device, the probable cause or causes
of the failure, and the corrective action to take for correcting the failure. Much
of the corrective action calls either for taking a device or devices off-line or for
removing power from the enclosure containing the failed device.
WARNING
Take all ESD and safety precautions when handling the devices, more
specifically, when taking a device off-line or when removing a device.
Failure to do so will damage the device.
Use the following basic steps for all troubleshooting that you perform for the
Rx7x disk ISE in an SF7x storage enclosure, as it resides in an Sx300 storage
array:
1. Inspect the ISE’s operator control panel (OCP). Is a Fault indicator lit? If
so, press the Fault button and read the error code.
2. Access the ISE in question. Open the front or rear of the SF7x enclosure
and gain access to the ISE’s various cables and check that they are seated
correctly.
3. Run various tests on the ISE by using DUP.
