Hi All,

 

I have a Dell T420 tower server and it's only about a year old, but I took the front 'security' bezel off yesterday to use the front USB ports and noticed that one of the drives is blinking amber for half a second, then green, then repeats.

 

I've researched this and it may indicate a drive failure is imminent... :eek:

 

I didn't build it, it came pre-built from Dell, but with no OS (I installed that myself).

 

There are 2 x 300GB SAS 6Gbps, 3.5-in, 15K RPM Hard Drives (Hot Plug) - DELL PERC H310 RAID CONTROLLER - RAID 1 (I think).

 

This is where the OS is installed.

 

Are there any Dell utilities (specific to my server) that I need to download and install to perform some diagnostics or provide evidence to Dell?

 

As you can tell I have never had to replace a drive on a production server before so I am REALLY nervous! :(

Should have the Dell Open Manage software installed. (if Windows OS)

 

Is there not a LCD screen on the server? That would give you a message to say whats is going on?

Make sure you double check the set up of the RAID array with a fine tooth comb first using either something like Openmanage, or by actually rebooting the server at a quiet period (may not be possible) and going into the raid controller bios setup.

 

Last thing you want to do is pull a drive and replace because you though it was a raid1 array, only to then find it was actually a raid 0 array and you've just lost all your data.

 

Also, backups - make sure you get solid backups and preferably test a restore onto another device just to make sure.

+1 on installing openmanage to look at the RAID setup, its a VERY good tool for keeping an eye on your Dell kit.

i believe idrac allows some you to view options about how the raid is setup.

Yes, there is a small LCD screen - it just has its usual number (not lit up or flashing or anything).

I'm really, really hoping they wouldn't have ordered a server set up with a RAID 0 array, but I will double check. Can't reboot until next week, but I was hoping to start the ball rolling with Dell, just so I can be sure the replacement arrives and I can get it installed and tested during half-term.

 

Unfortunately I have no way to test the back-ups and sadly the last couple have failed!

From memory I think there is also RAID card software for svr2012r2 which may give more info. We have a perc h700 card on our r420. As mentioned idrac is pretty good but you may need the enterprise version for bells and whistles. If you can, set it to email errors.

As mentioned -backups before anything else! Veeam free may be you friend.

Can't even install it....

 

Prerequisite checker cannot run .vbs files - There is no script engine for file extension ".vbs".

 

An error occurred while attempting to execute a Visual Basic Script. Please confirm that Visual Basic files are installed correctly.

 

In the help files it says: Maybe WSH is the wrong version, corrupted, or not installed. Download WSH from msdn.microsoft.com.

 

I am giving up! Maybe I will be a bit more willing Monday morning......... :getmecoat:

I inherited a Dell R515 server which at one point was experiencing multiple drives with predictive failures, seems to have settled down now and luckily had 1 drive set as a hot spare.

The one thing that annoys me is when Dell (or HP for our other servers) say have you ran the diagnostics tool etc etc in case it's a backplane issue,

Well if it says the drive has failed, its failed.

Dell told me as I had 3 fairly close drive failures they wanted to come out and replace the backplane. I told them no need, they are drive failures. Year and a half one it' all been fine with no failures.

Well, the very nice man at Dell looked through the logs and decided he would send me 3 new drives.... 3 NEW DRIVES!!!!!

 

I'm hoping it's just a case of powering down, swapping the drive and letting it rebuild itself?

 

The only problem is, he's decided I need to replace BOTH system drives and one from the DATA array due to an error it had last May, (that's RAID 10, so should be just the same procedure hopefully).

 

The server hasn't even finished its one time emergency full back-up and the delivery man is coming back tomorrow to pick up the faulty drives... Oh yes he is...

 

Work in a school they said, think of all the holidays they said - busiest, most stressful time of my year (can't wait for them to come back so I can resume concentrating on changing toner cartridges and turning things off and on again)!

Take it easy man do the drives one at a time, just tell them it will take 24 hours to install and check each drive and so you won't be able to have the faulty ones collected until next Wednesday.

 

Remember, these guys work for you, not the other way round!
