CLI Guide

missing-lun-response notready|illegal
Optional. Some operating systems do not look beyond LUN 0 if they do not find a LUN 0 or cannot handle
noncontiguous LUNs. This parameter handles these situations by enabling the host drivers to continue
probing for LUNs until they reach the LUN to which they have access. This parameter controls the SCSI
sense data returned for volumes that are not accessible because they don’t exist or have been hidden
through volume mapping (this does not apply to volumes of offline disk groups). Use the default option,
notready, unless the system is used in a VMware environment or a service technician asks you to change it to
work around a problem.
• not ready: 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. If the system is used in a VMware environment, use this option.
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 to continue using its current caching mode for better performance.
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.
• 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.
restart-on-capi-fail enabled|disabled|on|off
Optional. Sets whether a Storage Controller that experiences a CAPI hang will be forced to restart. This is
disabled by default. A CAPI hang is perceived as a management-interface hang. As part of the restart
process, a dump file is created and event 107 is logged. To provide the dump file to technical support for
debugging, use the Save Logs action in the PowerVault Manager.
single-controller
For use by a service technician only.
Optional. For a system that lacks a second controller module for redundancy 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.
smart enabled|disabled|on|off|detect-only
Optional. Enables or disables SMART (Self-Monitoring Analysis and Reporting Technology) monitoring for all
disks in the storage system. When SMART is enabled, the system checks for SMART events one minute
after a restart and every five minutes thereafter. SMART events are recorded in the event log.
• disabled or off:Disables SMART for all disks in the system and for all disks added to the system.
• enabled or on:Enables SMART for all disks in the system and for all disks added to the system. This is
the default.
• detect-only: Detects but does not change the SMART setting of each disk in the system, and for
each new disk added to the system.
