Sramretentiontest - HP StorageWorks 2/64 - Core Switch Command Reference Manual

sramRetentionTest

Performs a data retention test of the miscellaneous SRAMs in ASIC.
Synopsis
sramretentiontest [--slot slotnumber][-passcnt count][-ports
itemlist][-skip bitmask][-delay value]
Availability
admin
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. The test will use four QUAD_FILL patterns and one QUAD_RAMP pattern
with random seed. The first four QUAD_FILL patterns are:
0xffffffff
0x55555555
0x33333333
0x0f0f0f0f0f

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.
Specify the number of times to execute this test. The default value is 1.
Specify a list of blade ports to test. By default, all the blade ports in the
specified slot are used. See
Specify patterns to omit in the test. This command uses the data patterns
described in the section above by default. Using this option, you can
intentionally omit one or more patterns, if needed.
Specify the delay between the read and write, in seconds. The default value
is 10 seconds.
