HD RAID Configuration Mode Commands


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
