HD RAID Configuration Mode Commands This mode develops default policies designed to minimize administrative intervention when setting up the RAID on ASR 5000 SMC hard disks. end Exits the current configuration mode and returns to the Exec mode. Product All Privilege Security Administrator, Administrator Syntax end Usage Use this command to return to the Exec mode. exit Exits the current mode and returns to the parent configuration mode. Product All Privilege Security Administrator, Administrator Syntax exit Usage Use this command to return to the parent configuration 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
