sramRetentionTest 2 sramRetentionTest Performs a data retention test of the miscellaneous SRAMs in ASIC. Synopsis sramretentiontest [--slot slotnumber][-passcnt count][-ports itemlist][-skip bitmask][-delay value] Description Use this command to verify that data written into the miscellaneous SRAMs in the ASIC are retained after a 10-second wait. The method used is to write a fill pattern to all SRAMs, wait 10 seconds, and then read all SRAMs, checking that the data read matches the data previously written. The test is repeated using the inverted version of the pattern. For details about the patterns used in diagnostic tests, refer to the dataTypeShow command. The sramRetentionTest command cannot be executed on an operational switch. You must first disable the switch using the switchDisable command. The command is supported only on Brocade 200E, 3250, 3850, 3900,4100, 24000, and 48000 platforms; use turboRamTest instead. The execution of this command is subject to Admin Domain restrictions that may be in place. Operands This command has the following operand: --slot slotnumber Specify the number of the slot on which the diagnostic operates. The ports specified are relative to this slot number. The default is set to 0 and designed to operate on fixed-port-count products. -passcnt count Specify the number of times to execute this test. The default value is 1. -ports itemlist Specify a list of blade ports to test. By default, all the blade ports in the specified slot are used. Refer to itemList for more details. -skip bitmask Specify patterns to omit in the test. Using this option, you can intentionally omit one or more patterns if needed. This command uses the following data patterns: 0x01 Skip BISR/BIST test 0x02 Skip central memory WR/RD by way of the embedded port test 0x04 Skip central memory WR/RD by way of the special memory interface test 0x08 Skip ASIC interconnect test 0x10 Skip parity error detection test 0x20 Skip loom-only buffer number error detection test 0x40 Skip loom-only chip number error detection test 0x80 Skip data retention test -delay value Specify the delay between the read and write, in seconds. The default value is 10 seconds. Examples To run a data retention test: switch:admin> sramretentiontest 2 Running SRAM Retention Test ... passed. Fabric OS Command Reference Manual 645 53-1000436-01
