Testing The Array With Stortools; Identifying Miscabled Partner Groups - Sun Microsystems StorEdge T3 Service Manual

Note – The fru stat command reports temperature readings on the interconnect
cards, controller board, disk drives, and PCUs. For the PCU, the fru stat output
does not display a temperature value, but reports a normal value. For all other
FRUs, fru stat reports a numerical temperature.
System firmware monitors only the temperature state reported by the PCUs. This
means a high temperature reading on an interconnect card, for example, will not
cause the firmware to take evasive action (such as powering off the array).

Testing the Array With StorTools

Access the StorTools main menu through the stormenu command. Once executed,
this command runs the initcheck program to identify any failing loops that could
cause a program to hang. initcheck runs a quick loop back frame (lbf) test and
performs disk inquiries.
Note – Since lbf is not supported on PCI FC-100 host board adapters, initcheck
performs disk inquiries only on those systems.
Consult your StorTools documentation for information on how to perform StorTools
diagnostic tests.
Note – The StorTools diagnostic package expects the software and firmware files to
be at certain minimum revision levels to run the tools. Always use the Check
Revisions selection and ensure that the system is up to the minimum revision
requirements before using any of the other main menu selections.

Identifying Miscabled Partner Groups

If a partner group has booted successfully but is unable to establish a Telnet
connection with the management host, the partner group might be cabled together
incorrectly.
The interconnect cable connections between dual controller units are critical for
determining which unit is the master controller and which is the alternate master. If
the interconnect cables are not properly installed on the interconnect cards, the top
