independent-cache enabled|disabled|on|off
Optional. Sets the cache redundancy mode for a dual-controller storage system. For the change to
take effect, you must restart both Storage Controllers.
•
disabled
or
off
: Controller failover is enabled and data in a controller’s write-back cache is
mirrored to the partner controller. This is the default.
•
enabled
or
on
: The controllers use Independent Cache Performance Mode, in which controller
failover is disabled and data in a controller’s write-back cache is not mirrored to the partner
controller. This improves write performance at the risk of losing unwritten data if a controller
failure occurs while there is data in controller cache. You cannot enable this parameter if the
single-controller
parameter is enabled.
managed-logs enabled|disabled|on|off
Optional. Enables or disables the managed logs feature, which allows log files to be transferred
from the storage system to a log collection system to avoid losing diagnostic data.
•
disabled
or
off
: The managed logs feature is disabled. This is the default.
•
enabled
or
on
: The managed logs feature is enabled.
missing-lun-response notready|illegal
Optional. Sets whether host drivers may probe for LUNs until the host drivers reach the LUN to which
they have access.
•
notready
: Sends a reply that there is a LUN where a gap has been created but that it’s “not
ready.” Sense data returned is sensekey = 2, code = 4, qualifier = 3. This option is the default.
•
illegal
: Sends a reply that there is a LUN but that the request is “illegal.” Sense data returned
is sensekey = 5, code = 25h, qualifier = 0.
partner-firmware-upgrade enabled|disabled|on|off
Optional. Sets whether component firmware versions are monitored and will be automatically
updated on the partner controller.
•
disabled
or
off
: Partner firmware upgrade is disabled.
•
enabled
or
on
: Partner firmware upgrade is enabled. This is the default.
partner-notify enabled|disabled|on|off
Optional. Sets whether to notify the partner controller that a trigger condition occurred. Enable this
option to have the partner also change to write-through mode for better data protection. Disable this
option to allow the partner continue using its current caching mode for better performance. The
default is
disabled
.
•
disabled
or
off
: Notification is disabled. This is the default.
•
enabled
or
on
: Notification is enabled.
power-supply-failure enabled|disabled|on|off
Optional. Sets whether the cache policy automatically changes to write-through when a power
supply fails.
•
disabled
or
off
: The power-supply failure trigger is disabled. This is the default.
•
enabled
or
on
: The power-supply failure trigger is enabled.
single-controller
Optional; for use by a service technician only. For a 2U12 or 2U24 system that had two controller
modules but now has only one and is intended to be used as a single-controller system, this
parameter changes the operating/redundancy mode to Single Controller. This prevents the system
from reporting the absent partner controller as an error condition. This parameter does not affect any
other system settings. Installing a second, functional controller module will change the mode to
Active-Active ULP. You cannot enable this parameter if the
independent-cache
parameter is
enabled.
