backplaneTest Tests the backplane connection for a multiple-blade configured system. Synopsis backplanetest [--slot number][-passcnt count][-payload value][-pat type][-ports itemlist][-[-verbose mode] Availability admin Description Use this command to verify the backplane connection for each blade through the backend external (BE) ports. This command can run only on a multiple-blade configured system. It assumes that all blades available on the specified switch have passed the blade diagnostics tests. This command verifies the backplane connection by using a functional blade's frame transmitter and receiver features. NOTE: No other diagnostic can be executed until this test is completed. This command is supported on the SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, Core Switch 2/64, and SAN Director 2/128. This command is not supported on the 4/16 SAN Switch, SAN Switch 4/32 and 4/256 SAN Director, which use the Condor ASIC. Operands This command has the following operands: --slot number -passcnt count -payload value -pat type -ports itemlist -verbose mode Specifies the slot on which the diagnostic operates. The ports specified are relative to this slot number. Specifies the number of times to perform this test. The default value is 1. Specifies the byte size of the test frame payload. The payload size must be in multiples of 4, and the minimum size is 16. The default value is 512 bytes. Specifies the test-pattern type to use in the test frame payload. Twenty types of predefined patterns are provided with the test; the default is jCRPAT (type=17). Use dataTypeShow to display the pattern types supported with backplaneTest. Specifies a list of blade ports to test. By default, all the blade ports in the specified slot are used. See itemList for further details Specifies verbose mode. If specified with a nonzero value, this mode displays the test progress in detail. The default value is to disable the mode. This operand is optional. 54 Fabric OS commands
