Note: This area only applies to larger models (such as 3000) that include multiple hot-swap disks in a RAID-5 configuration.
Note: The pages in this area may load somewhat slowly as they collect information from the RAID controller.
Little to no maintenance of the RAID array is required. In the event
of a disk failure the hot-spare will automatically take over and the
array will be automatically rebuilt. The rebuild process takes several
hours. After the array is rebuilt the failed disk will have to be
manually removed (no shutdown required) and replaced with a same size
or larger disk of the same type. After the disk is replaced it
needs to be
Added to the array.
RAID Status page displays a summary of the RAID's state.
It's an abbreviated form of the information on the RAID Management
page to provide a quick Good/Bad check.
RAID Management page lists information about the overall
RAID array as well as each of the hard disks in the system. Each
item starts with a Status and is color-coded to indicate its state.
Green is good, red is problem, blue is hot-spare disk, light blue
is unused disk, yellow is verifying/testing.
The first line of the Storage table contains information about the
overall array with the
Use column set to
The remaining lines are individual disks, either
None. Member disks are part of the RAID array.
Spare disks are hot-spares that will take over for a failed member disk.
Each item in the Storage table has associated actions that may be taken.
None. All arrays should have a hot spare.
Noneto the array as a hot-spare.
The first number in the
Disk:Addr column (everything up to the :)
is the disk number which corresponds to labels on the front panel of
the Search Appliance.
The Rebuild/Verify Rate is how aggressively the RAID will rebuild. A higher rate will rebuild a partially failed array more quickly so that it's in a non-fault-tolerant state for the shortest possible time. The downside of the higher rate is that operations that use the disk such as walks and searches will see slower performance.
This table shows various model and version information about the RAID controller.
The Command input box should not be used except at the request of Thunderstone technical support. It is for issuing arbitrary commands to the RAID controller. Putting the wrong thing in this field could irrevocably damage the RAID array and render your machine completely unusable! If the "Ok to run this command" checkbox is not also checked anything in the command input will be ignore.
The Perform button at the bottom will perform all of the actions selected on the form. You must also set "Are you sure you want to perform these actions?" to "Yes" or the actions will not be performed.
This provides a rough approximation to the physical front panel of the Search Appliance. It shows the drive arrangement to aid in locating the proper disk when performing maintenance.
