CLI Guide

• disabled or off:The CompactFlash failure trigger is disabled.
• enabled or on: The CompactFlash failure trigger is enabled. This is the default.
controller-failure enabled|disabled|on|off
Optional. Sets whether the cache policy will change from write-back to write-through when a controller fails.
• disabled or off: The controller failure trigger is disabled. This is the default.
• enabled or on: The controller failure trigger is enabled.
dynamic-spares enabled|disabled|on|off
Optional. Enables or disables the dynamic spares feature. This feature lets you use all of your disks in fault-
tolerant disk groups without designating a disk as a spare. With dynamic spares enabled, if a disk fails and you
replace it with a compatible disk, the storage system rescans the bus, finds the new disk, automatically
designates it a spare, and starts reconstructing the disk group. A compatible disk has enough capacity to
replace the failed disk and is the same type. If a spare or available compatible disk is already present, the
dynamic spares feature uses that disk to start the reconstruction and the replacement disk can be used for
another purpose.
• disabled or off: The dynamic spares feature is disabled. This is the default.
• enabled or on: The dynamic spares feature is enabled.
emp-poll-rate rate
Optional. Sets the interval at which the storage system will poll each enclosure's Enclosure Management
Processor (EMP) for status changes, from 5 to 3600 seconds. Typically you can use the default, 5 seconds.
• Increasing the interval might slightly improve processing efficiency, but changes in device status are
communicated less frequently. For example, this increases the amount of time before LEDs are updated
to reflect status changes.
• Decreasing the interval slightly decreases processing efficiency, but changes in device status are
communicated more frequently. For example, this decreases the amount of time before LEDs are updated
to reflect status changes.
fan-failure enabled|disabled|on|off
Optional. Sets whether the cache policy will change from write-back to write-through when a fan fails.
• disabled or off: The fan failure trigger is disabled. This is the default.
• enabled or on: The fan failure trigger is enabled.
host-cache-control enabled|disabled|on|off
Optional. Sets whether hosts are allowed to use the SCSI MODE SELECT command to change the storage
system's write-back cache setting.
• disabled or off: Host control of caching is disabled. This is the default.
• enabled or on: Host control of caching is enabled.
large-pools enabled|disabled|on|off
Optional. Enables or disables the capability to create a virtual pool larger than 512 TiB on each controller by
limiting the number of user-defined snapshots that can be created in snapshot trees.
• disabled or off: The maximum size for a virtual pool will be 512 TiB. The maximum number of volumes
per snapshot tree will be 255 (base volume plus 254 snapshots). This is the default. You can disable this
setting only if each pool is less than 512 TiB.
• enabled or on: The maximum size for a virtual pool will be 1024 TiB (1 PiB). The maximum number of
volumes per snapshot tree will be 9 (base volume plus 8 snapshots). You can enable this setting only if no
snapshot tree has more than 15 volumes.
Changing the large-pools setting will automatically restart both controllers, during which time data will be
unavailable.
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.
