CX3-10 Hard Disks
Hi
We have an enclosure CX3-10 and failed 2 disks, 1 of the first grupo of disk (from left to right) an other of the other grupo (see picture)
- Do you know who can sold us these disks in mexico city?
- Is there a special consideration to change these disks? or only I have to remove and put the new disk.
I hope to know news

The first 5 drives in the enclosure starting from the left are the array Operating System Drives - these you must be very careful with. From the picture it looks like 4th drive is faulted (this would be Bus 0 Enclosure 0 Disk 4 or 0-0-3).
The drives used are from EMC and are formatted with a special format that is not standard, so you must get a replacement that is an EMC disk. There should be a part number on the front of the disk. The position of the drives is also very important - you can not take one of the first 5 disks and move it to another position or the whole array will stop working.
There should be an EMC Partner located in Mexico - they should be able to help with replacing the disk that failed based on the part number.

Hi Glen
We're working to get the exact type of disk, but I'm scared because you told me that It disk MUST be replaced only by a partner of EMC????
If I get another disk (same brand, type and model) I can not unplug the old and plug the new one???
Did I understand well?

Correct. You cannot use an off-the-shelf disk to replace a failed EMC disk. EMC specially formats its disks in such a way that a non-EMC disk cannot be used. If insert a third-party disk, the CX3 will not recognize it and will not rebuild on it.
You will need to buy a disk from EMC or an EMC-authorized service partner. Save yourself a great deal of grief and contact one of them.
Let us know if that helps!

As long as the other 4 vault drives are OK you should not have any trouble replacing the faulted drive.
The other drives appear to be CX-4G15-300, so make sure you have a matching EMC formatted drive available.
The first 5 drives contain the array software, so when you replace the drive, the array will automatically rebuild the array software on the new drive along with any other luns you have allocated there.
I have swapped out the entire vault drive set, one at a time on several CX3/CX4 arrays, and even changed drive sizes while doing this. The minimum drive vault drive size for a CX3 is 36Gb, but I often resize my vault drives to the 72Gb drives in order to keep the larger drives available for user luns. I also do not store any user luns on the vault drives, although this is supported I prefer to keep them isolated in "Raid Group 0". This helps minimize the rebuild time should another vault drive fault and require swapping. The rebuild times are faster if no user data is on the vault drives.
As for vendors, have you checked ebay? Ive had pretty good luck there with drives, probably around 90% are good when I receive them.

Hi,
I am working in Saudi Arabia, I have also one HDD Failed. I am facing a big problem to get EMC formatted hard drive.
Currently old EMC Storage HDDs are not available, so I will strongly recommend you, if you got person who is agreed to provide you the HDD you should buy extra 2 or 3 to save feature problem. If your storage more than 6-7 year old don't put any important data on it.
Regards
