How is this possible?

Trying to wrap my head around this problem. Hoping the combined intelligence at TE can help me out.

How can a SAN admin who logs into the management console on a regular bases not notice 3 disks failing over 4 months time?

We have hundreds of drives, we rely on the HITRAK server to alarm if their is a drive failure. This is actually a requirement to get Hitachi support, when there is a failure the server automatically opens a service request with Hitachi.

If we didn't have a monitor then there is a very good possibility that a bad drive would go unnoticed. We rarely look at the individual disks in the DP's and the physical disks are covered by a bezel so you wouldn't necessarily see a bad drive LED.

And on top of this, any comptent storage admin would have his storage arrays actively monitored. I certainly had my SAN configured and would receive alerts on everything from temperature, to open bays, degraded array status, failures etc.

I am not excusing the person who missed three bad drives. I am just saying I understand how they could be missed if you are not looking for them.
