Re-enable a failed RAID Array HP410 – Logical Drive Failure

by | Sep 12, 2021

To re-enable a failed RAID Array HP410 we remove the affected drive for 10 seconds and then re-insert it.

As part of our Server Management Services, we assist our customers with several RAID Array queries.

Today, let us see how we can perform this task.

Re-enable a failed RAID Array HP410

Generally, if we have drives that does not support a low latency error recovery a disk will drop out a RAID array.

In such a case, we will receive an alarm in ESX or the operating system that says the Logical Drive has failed.

In addition, there is a chance for a physical drive failure too.

Moving ahead, let us see how our Support Techs fix this issue.

As we saw, to recover from the problem we need to remove the affected drive and then re-insert it.

We can perform this while the system boots into the array management software.

Once the physical drive recognise as operational again we can take steps to recover the logical drive.

In this case, we will use the ESX. However, any other operating system that can use the hpssacli utility should be the same.

First we check the status of the logical drive:

hpssacli ctrl slot=0 ld 1 show status
logicaldrive 1 (14.6 TB, 0): Failed

Then we re-enable the logical drive:

hpssacli ctrl slot=0 ld 1 modify reenable forced

After that, we check the logical drive again:

hpssacli ctrl slot=0 ld 1 show status
logicaldrive 1 (14.6 TB, 0): OK

In most case, the solution is to use drives that support a lower recovery latency. This includes WD Reds.
