In redundant-controller configurations, these commands affect all LUNs on both controllers. This might result in data loss unless all I/O activity is suspended by halting all applications that are accessing the array, and unmounting any file systems that are mounted from the array. The controller must be reset for this command to take effect.Ĭaution - All reset commands cause the array to stop responding to I/O requests from the host for a period of time. To avoid the possibility of data corruption, set the write policy to write-through. The set cache-parameters command sets cache policy (write-back or write-through), optimization mode (sequential or random), and a periodic cache synchronization value.Ĭaution - Data inconsistency can occur when a controller configured with one optimization mode is used to replace a failed controller with a different mode.Ĭaution - In a single-controller configuration, if you set the cache policy to write-back, data corruption might occur in the event of a controller failure. Sccli: /dev/rdsk/c0t5d0s2: device is ready Sccli: /dev/rdsk/c0t5d0s2: waiting for device to be ready Data loss may occur if the controller is currently in use.ĭo you want to reset the controller now? y sccli: resetting controller.
#Command line find file controller Offline#
The controller will go offline for several minutes. # sccli /dev/rdsk/c0t5d0s2 reset controller WARNING: This is a potentially dangerous operation. Note - This command prompts the user to confirm the failure, unless the -yes option is specified. Note - Before running this command, perform a show redundancy-mode command to make sure a secondary controller exists. If the controller is configured for failover, the inter-controller link is not disconnected with this command. The fail command simulates a controller failure and causes all the LUNs assigned to the specified controller to fail over to the redundant controller, if it is configured for failover. After running a resetcommand, to stay in prompt mode, run the selectcommand to reselect the device.
If this option is not specified, RAID sets are not created, and the configuration will not be completely restored.Ĭaution - All reset commands cause the array to stop responding to I/O requests from the host for a period of time. Rebuild RAID sets specified in the saved configuration.
#Command line find file controller download#
TABLE 3-1 Arguments for download controller-configuration Note - Optimally, rebuild any logical drives before running this command.ĭownload controller-configuration filename The command provides an option to specify whether to build the logical drive.Ĭaution - The download controller-configurationcommand unmaps all existing logical drives if they do not match the configuration file that is being downloaded. However, creating a logical drive might take a long time, and block other operations. The configuraton file includes channel settings host and drive side parameters array parameters network port setup controller general parameters logical drive, logical volume, and physical drive information partition information and mappings on host channels.Ī logical drive or logical volume create operation might be required to completely restore the saved configuration. The download controller-configuration command restores controller configuration information previously saved using the upload controller-configuration command. In active/active configurations where LUNs are assigned to both the primary and secondary controllers, a Sun StorEdge CLI command can be used only with those LUNs assigned to the primary controller.ĭownload controller-configuration Description
Note - The secondary controller in dual-controller configurations does not support any administrative functions.
