> HD RAID Configuration Mode Commands
> This mode develops default policies designed to minimize administrative intervention when setting up a RAID on ASR 5000 SMC hard disks.
> default
> Sets or restores the default condition for the selected parameter
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> default ( overwrite { invalid | unknown | valid } disk | select }
> overwrite { invalid | unknown | valid } disk
> Configures the system to overwrite any of the disk types
> select
> Selects the newer of the valid RAID disks when two valid RAID disks are available.
> Usage
> Selects default parameters
> Example
> Use the following example to select the newest disk in an SMC pair:
> default select
> end
> Exits the HD RAID configuration mode and returns to the Exec mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> end
> Usage
> Change the mode back to the Exec mode.
> exit
> Exits the HD RAID configuration mode and returns to the previous mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> exit
> Usage
> Return to the previous mode.
> overwrite
> Sets the RAID overwrite properties.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> [ no | default ] overwrite { invalid | unknown | valid } disk [ -noconfirm ]
> no
> Prevents a disk from being overwritten.
> default
> Configures the default overwrite action:
> invalid
> This option allows the system to automatically overwrite invalid disks including empty disks, wrongly partitioned disks, and partially constructed disks.
> This is the default overwrite action.
> unknown
> This option allows the system to automatically overwrite unknown disks that has a valid RAID superblock but is not configured in the standard way; most likely because it has data from a different version.
> valid
> This option allows the system to automatically overwrite a disk that is a clean RAID component but not part of the current or selected RAID.
> -noconfirm
> Indicates that the command is to execute without any additional prompt and confirmation from the user.
> Usage
> Sets a policy for automatically overwriting different disk types. If there is a disk that satisfies the changed overwrite policy then the disk would overwrite immediately.
> Example
> The following command configures a policy for overwriting invalid RAID disks:
> overwrite invalid disk -noconfirm
> select
> Configures the disk preference when both hard disks on the ASR 5000 have valid RAID information.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> [ default ] select { newer | none } disk [ -noconfirm ]
> default
> Configures the command to its default condition.
> newer
> Selects the newer disk by timestamp and event counter in superblocks. If all are the same, then the same array will start with both SMC disks, but a different array will need admin intervention).
> none
> Does not select any disk but defers to administrator intervention.
> -noconfirm
> Indicates that the command is to execute without any additional prompt and confirmation from the user.
> Usage
> Determines the selected disc when two valid disks from either the same or different RAIDs are running on the ASR 5000.
> Example
> This command forces the RAID to be configured on the newer SMC hard disk:
> select newer disk -noconfirm
