How to Tell if Dell EqualLogic Controller has Failed If you remove the active control module, there will be a short interruption as failover to the secondary control module occurs. You can order a blank control module from your PS Series array service provider.

#Equallogic ps4100 battery status failed install#

If an array will operate for a long time with only one control module, you must install a blank control module in the empty slot.

NOTE: For proper cooling, do not leave a control module slot empty.

If a control module fails, replace it as soon as possible with the same control module type.Ĭaution: Do not mix control module types in an array.įor information about replacing a control module, see the Hardware Maintenance manual for your array model or contact your array support provider.ĭo not remove a failed control module until you have a replacement. If the only functioning control module fails, the controller will be inaccessible from the network and data loss is possible.

If there is a network connection to the active control module, the control module failover will be transparent to applications however, iSCSI initiators must reconnect to the group IP address. In a dual control module array, if the active control module fails, the secondary control module automatically takes over and become active. In a dual control module array, if the secondary control module is removed or fails, the remaining control module may enter write-through mode depending on the cache mode policies. SPS Pros is not responsible for faults, failures, data loss, etc. Please see the Hardware Maintenance manual for your array model for detailed information about array-specific control module and network failover behavior. The procedures may vary when a control module (member) is removed or fails depending on the number and type of control modules, the network cabling configuration, and the cache mode settings.

EqualLogic Battery Status Failed – How to Fix.

How to Replace a Dell EqualLogic Controller.

The default is Write-back however, the array will be configured to Write-thru whenever there is a battery failure. The mode that the Read/Write cache is currently in within the array. The size in MB of the Read/Write cache within the array. The total number of disks that have been installed in the array. The number of controller modules in the array. The number of disks allocated as spares in an array. Specifies whether there are lost blocks in the RAID array which the user may want to clear. This value is expressed as a percentage and is calculated by dividing the UsedStorage value by the TotalStorage value and then multiplying the result by 100.Īre There Lost RAID Blocks To Be Cleared?

Mirroring - Indicates that a bad drive is being mirrored onto a spare drive.

This means that administrator intervention is required to correct the problem.

Catastrophic Loss - This may not be visible to the user since the RAID may not be able to start up.

Failed - The RAID experienced a failure, possibly due to a failed drive with no spare being available.

Reconstructing - A drive is being reconstructed and displaying a percentage complete value.

Verifying - Running a verification pass and displaying a percentage complete value.

Degraded - The RAID is in a degraded state, possibly because no spares are available.
