Can you upgrade a Lefthand / HP SAN Node's Hard Drives?
According to HP support the answer is YES!!
Here is what I have learned so far. Yes, you can upgrade your SAN node hard drives simply by replacing the drives with new larger drives and then re-imaging the node with the latest SAN/iQ CD which you can download as an ISO.
I mainly have P4500 series units. I have three nodes that have 300GB SCSI drives. I can replace those with 600GB drives and essentially double my storage space. I could even go with 1TB or 2TB drives and grow it even larger. However those are "Midline" drives and you take a 40% performance hit according to HP support. As of right now the biggest 15K SCSI drives they support are the 600GB drives. The 1 or 2 TB drives are 7.2K RPM. To keep HP happy and maintain service contracts you need to use the HP specific drives.
Another interesting note is that I can even take my SATA SAN and put in SCSI drives to make it a SCSI (SAS) SAN. Nice.
I'm posting this because I couldn't find anything on-line that even hinted that this was possible, let alone supported. So from the horses mouth (HP), it is, and if you do it right, it is even supported. What they do is that if you have a hard drive failure you will have to work with a different department for replacement hard drives. They have 3 year warranties. They may not fall under a 4-hour response time (if you have that level), I forgot to ask that.
That's all I'm going to post right now. If enough people are interested in the details I'll follow-up with part numbers, the process, etc.
