Options for a bad Raid - 5 Parity disk
Hello:
We have a SAN where were have 12 different drives seperated into 2 partitions.
The 1st partiton is for backups only (raid-5).
The 2nd partiton is for our VmWare productions side (raid-5).
We have a little bit more that half of our servers converted to VmWare. Recently a hard drive went bad on the production side (Raid-5). The spare Raid-5 hard drive kicked an and we are ok; but, it is taking a long time to get a replacement drive. The slowness is because of the manufacturing problems in Asia.
First the supplier sent us the wrong size hard drive.
then, second our supplier ordered the correct hard drive for us; but it will take about 45 days for it to get to us.
My question is what are my options on how to replace the bad hard drive sooner? I am just worried if another har ddrive goes bad, then... that would be very bad.
Should I just get a bigger size hard drive than what the other hard drives are(in the SAN)? Or should I just keep looking to get the correct size and hope I can find something sooner?
I am afraid if I use a different size hard drive, then there might be incompatablility issues later.
We use an HP StorageWorks MSA 1500 Array Controller. Along with an HP Storageworks MSA 20 Hard Drive cage.

Ok,
1. The bad hard drive in question is an HP:
a. 500 GB
b. SATA MDL
c. 7.2 K speed
d. spare number: 45319-001
2. The 1 TB hard drive that I have here, has the followin specs:
a. 1 TB
b. SATA MDL
c. 3G 7.2 speed
d. spare number454273-001
3. I am trying to contact HP and see if this will work; but, the speed for the 1 TB SATA states "3G 7.2K" the original disk is "7.2K".
Will this replacement disk work?

I just confirmed with HP that the 1TB drive should work for this.
Thank you to everyone invovled with this question.

2. The order is from HP and I spoke with their customer service directly. They told me 45 days until arrival.
3. The bad hard drive in question is an HP:
a. 500 GB
b. SATA MDL
c. 72 K
4. So, in theory we should be ok, if I use an HP:
a. 1 TB.
b. SATA MDL
c. 72 K
... to replace the bad drive.
What about if the MSA Hard Cage has a different firmware version than the new hard drive? Will that make a difference? I am just trying to avoid a potential disaster.
