/c
x
set selftest=enable|disable
[task=UDMA|SMART]
This command enables or disables all selftest tasks or a particular
selftest_task (UDMA or SMART).
The selftest schedule is always enabled.
For 3ware RAID controllers older than the 9690SA, two self-tests can be set:
one to check whether UDMA Mode can be upgraded (applies to PATA drives
only) , and another to check whether SMART thresholds have been exceeded.
For the 9690SA, you can only check the SMART thresholds for drives.
7000/8000 series have the same internal schedule, but it is not viewable or
changeable.
Example:
//localhost> /c0 selftest=enable task=UDMA
enables UDMA selftest on controller c0.
/c
x
set exportjbod=on|off
The JBOD Export Policy is only supported on 9000-series controllers.
Previous models did not have such a policy enforcement feature.
This command allows you to set the JBOD Export Policy to
on
or
off
. By
default, exportjbod is
off
.
If the JBOD export policy is
off,
CLI will not be able to create JBODs. During
reboot, firmware will not export JBOD units to the operating system.
A JBOD is an unconfigured disk attached to your 3ware RAID controller.
AMCC recommends that you use Single Disk as a replacement for JBOD, to
take advantage of features such as RAID level migration.
Note:
SAS drives cannot be JBODs.
/c
x
set ondegrade=cacheoff|follow
This command is only for 9500S controllers.
This command allows you to set a controller-based write cache policy. If the
policy is set to
cacheoff
and a unit degrades, the firmware will disable the
write-cache on the degraded unit, regardless of what the unit-based write
cache policy is. If the policy is set to
follow
and a unit degrades, firmware will
follow whatever cache policy has been set for that unit. (For details about the
unit-based policy, see “/cx/ux set cache=on|off [quiet]” on page 86.)
