Options for a bad Raid - 5 Parity disk
Posted on 2012-04-13
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.
