Fabric OS 5.0.0 command reference guide 105
Tests the data retention of the central memory SRAMs.
Synopsis
cmemretentiontest [--slot slotnumber][-passcnt count][-datatype
type][-ports itemlist][-seed value]
Availability
admin
Description
Use this command to verify that data written into the central memory SRAMs in the ASIC pair is 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 to verify that the data read matches the data previously written. The process is then
repeated using the reverse version of the pattern.
NOTE: This command cannot be executed on an enabled switch. You must first disable the switch using
the switchDisable command.
Operands
This command has the following operands:
cmemRetentionTest
--slot
slotnumber
Specify the slot number on which the diagnostic will operate. The ports specified will
be relative to this slot number. The default is set to 0 and designed to operate on
fixed-port-count products.
Specify the number of test passes to run. By default, the test will be run one time.
Specify the type of data pattern to use. By default, type 9, QUAD_RAMP, is used. For
a complete list of supported data patterns, run the dataTypeShow command. Some
common settings are:
-passcnt
count
-datatype
type

-ports
itemlist
Specifies a list of blade ports to test. The ports list is translated into a matching quad
list before the test is run. By default, all the blade ports in the specified slot (--slot)
are tested. Refer to the itemList help pages for further details.
-seed
value
Specify the data pattern seed to be used. The default seed value is 0.
