amber warning led - dead disk?


Recommended Posts

Hi all,

This morning my Gen8 greeted me with a blinking amber colored led bar :-\

After some doodling inside the various HP tools, it became apparent that disk1 (15 months old) was defect or missing. (lovely conundrum...)

I took out the drive, and added it into a Win7 system to see what's up, and it shows as RAW now in the disk management tools.
Win7 immediately complained about a non formatted drive...
In the past I had a drive or two doing this, and one time was able to restore the drive back into ntfs, with the data recovered. Much to my surprise....

As this is a server disk, I'm not really want to do this, especially because I'm running RAID.
Anyone can chime in as to how this could happened, and how I can check if the drive is still OK, and this a nasty and unfortunate fluke.

As data related things go, it looks like the server will rebuild with a new disk replacement. Right?

Tips and tricks are welcomed,

Sorry, should have added that as well...
Win2012R2 Ess. as the OS, the 4 drives are set up as RAID10, so a total of 6Tb of 'workable' disk space.

I downloaded the dldiag app from the WD website, and running a full diag on the disk now. That takes appr. 5 hours for the 3Tb of sectors ;)
Strangely enough the s.m.a.r.t. quick test didn't find anything, but I never ever found that remotely useful on a hd....

As this drive was part of a RAID10 set chances are it would not be readable in a PC. Prior to pulling the drive did you look at iLo or the diagnostics in SSA? Many times that will point you to the error. Is the array rebuilding?

I'm looking for a spare monitor cable atm, so I can boot the server and look at iLo messages as well.
I have to move server to monitor or vv... ;)

I have to admit I didn't look at the SSA diags, but did ran the other HP diagnostic tools on the server.
The extended HD disk check will be finished in about two hours, will wait for that before I plug it back into the server.
After that I will reboot the server and have a look at the iLo messages and SSA.

cheers for the answers so far.

Hi again,

After a looong HD check it came out OK... So the drive seems to be fine according to the WD utility.. Saves me buying a new HD I hope.

So I put the disk back into the server, and rebooted into the SSA. According to the diag, logical drive 2 is queued for rebuilding.
I rebooted again and agreed on rebuilding the array. After restarting SSA it seems the array is rebuilding itself.

Will keep you posted on this.




p.s. Is this a fluke thing on the disk/array, or should I run a extended hardware test on the server?

After quite some time the rebuild was done, and rebooted the server again.
Logged into SSA once more, and dumped the various SSA checks on disk, but cannot see any strange warnings in these logs.
Also ran a additional  'compare check' on a part of the data and backup, and both sets were identical.

So it looks like all is well again. Still would like to know what can trigger this, just to be on the look out for other 'nasties'. ;)

Same amber light this morning. Now the same disk that was giving me issues before is 'kaput'.
Faulty from the start I guess. Bought a replacement, this will arrive tomorrow.

Note to all: check your logs once in a while, as it seems to contain interesting information..... ;) Duh!
Next time I will replace  a disk immediately, and not take any chances.

      Hi there,
      I am looking to get 2x512GB SSDs on a black friday deal with converters.
      As i understand i need to put these in slot 1 and 2 run them in Raid 0 so if they are 6Gbps each does that mean they will run at 12Gbps concurrently and also double the read/write speed?
      I currently have a 1TB SATA Disk running on b120i Smart controller so will i lose the ESXi i am running on it, Is there a way i can restore it all on the SSD's or better off clean installing?
      Can anyone recommend which brand SSDs and specs i should be looking at?

      I just received an unlocked Nokia Lumia 925 from Expansys-USA.com. They had the grey model in stock and that is what I received. I have a black Wireless Charging Plate on order as well (uue in a week or so).
      The Lumia 925 is an extremely well built device. It feels dense and slightly hefty (compared to the Samsung Ativ S it is replacing). However, it is feels far lighter than 920 when held in the hand.
      The aluminum band is excellent quality, and looks like it will hold up well after usage. The backing is a soft touch polycarbonate that is thin but feels sturdy. The AMOLED screen is amazing, and comes with an setting panel that allows tweaking of both colors and contrast. I am leaving it set to the default "Enhanced" colors as opposed to "Native" or "Vivid". Auto brightness works better than any previous device I have owned. The setting to enhance daylight operation seems to really help in direct sunlight. The speaker is in the rear but sometimes feels as if sound is coming from under the display. There is an equalizer with various settings and well as the option to apply and save a customized sound. Dolby Headphones is an option that can be turned on/off. I am using it on AT&T (4G speeds only, as my work provision SIM is not on an LTE plan). Speeds and signal strength are reported lower than expected. But I have not seen a real world impact. Wi-Fi support 5GHz and seems to be very solid in both reporting strength and actual usage. The Glance features is very nice and allows the device to display the time (and some minor information like sound profile and low battery indicators) when the screen is locked. It has some options: The time can display only for 15-minutes. Then it will disappear. It knows when it is in your pocket or in a bag and turns off the display completely, yet the time returns when you remove it from you pocket/bag. It can be set to always be on, but could affect battery life. Having an AMOLED screen should keep that from being a big issue. There are settings for night mode. Set a time to be considered "night" and the clock and other text shows pale red instead of pale white. Very cool. No software updates were needed when I got the device. Only some app updates from the Windows Store. Nokia software mainly. Nokia apps complement the phone and Windows Phone 8 nicely. The Nokia Smart Camera app is there and allows everything the 1020 can do, except those fancy manual controls. The low light performance blows me away. The 6th lens improves everything about the camera. Outside of the 1020, this is the best camera on the market, along with the 925 which adds a Xeon flash (this has a dual LED). 12GB were available of the 16GB onboard storage. After setting up my apps and podcasts, but no local music storage, I was left with 10GB+. More to come! I used the device until the battery died and will let it charge overnight. Thursday 07/25 will be my first full day of usage of the battery. It'll take me a few days to get an idea of true battery life under my usage conditions.
      What would you like to know?
