I ended up purchasing 24 more and did two other units. I've actually retired those units now but it got me over a hump for only $85 each (a little cheaper now.) I did not try 4TB drives. <br /><br />One thing that did catch me off guard was that I needed to upgrade the RAM in some of the nodes. I think they may have had 2GB and needed at least 4GB... ?

It was a phone call from a year ago with a very helpful tech. If I recall correctly, the tech didn't really recommend it for most people as it isn't for the faint of heart, but pressing him a little he said they would still support it, just not the hard drives (those would have to be replaced by me - they have 3 year warranties but no same day replacements.) <br /><br />It was not anything they advertised or even advocated I'm sure, but I still have HP contracts on them with 4 hour response time and I've used the contract at least a few times in the past year - mostly dead cache batteries. <br /><br />With or without their blessing, this is definitely a do-at-your-own-risk project. My suggestion is that if you are not comfortable doing it - don't. If you want HP's blessing to do it and now they won't now... then don't. It really wasn't all that hard - but you have to know what you're doing. I was a Compaq Accredited Systems Engineer (ASE) way back when, so I know my way around servers pretty well. <br /><br />Use this info at your own risk :) <br /><br />My best guess on your error message is that you have some volumes with RAID-5 network striping. This stripes your data across 3 or more nodes. You can't move from 3 to 2 nodes and maintain RAID-5. Only RAID-10 is supported with 2 nodes. I could do it because I purchased 2 new nodes and did a swap (I don't remember their terminology.) Doing a swap brings the new node into the fold and stripes data to it with the old one in place. Once done re-striping then I was able to remove the old node. You’d have to change all your volumes to RAID-10 to remove a node. <br />Brian Kayserhttps://www.blogger.com/profile/14553812295322745265noreply@blogger.comtag:blogger.com,1999:blog-7943835118979294771.post-16929114593922401202013-11-01T21:20:03.755-04:002013-11-01T21:20:03.755-04:00This comment has been removed by the author.Brian Kayserhttps://www.blogger.com/profile/14553812295322745265noreply@blogger.comtag:blogger.com,1999:blog-7943835118979294771.post-90528963715732420502013-11-01T19:10:54.926-04:002013-11-01T19:10:54.926-04:00I tried to take one of my 3 nodes out of the clust...I tried to take one of my 3 nodes out of the cluster today but got the following message: <br />The operation cannot be completed on volume 'Volume Name' because cluster "Cluster Name' can not support that replication level.

It would take a long time (at least 12 days if you did one drive a day) to only find out that it won't work. You could call HP and ask, but I doubt that is a common question and doubt the tech you get would even know. Maybe they would? If I were to guess, I would guess it would not work. Plus you'd have 12 days of poor performance. <br /><br />If you have multiple nodes in a cluster and you have enough space that you can remove one, that may work. If all your volumes are network-RAID you should be good. If you do a lot of network-RAID-Zero though, then you may not have enough. If all are mirrored, when you remove a node it just breaks the mirror. Don't break the mirror before hand, it will then just stripe between nodes. You want the data to come off the node you are removing. When you remove the node via the CMC it will do that for you. <br /><br />You of course are loosing your fault tolerance during the process but you could do it in just a few days. Keep track of all your old drives (and which slot they came out of) in case you need to fall-back for some reason. You could put them all back in and all should be fine again. <br /><br />To do it, you would need to remove the node from the cluster and management group. Depending on network RAID level, many of your volumes would restripe which could take a day. <br /><br />When the node is safely removed from the Management Group, swap in your new drives. Then image the node (that takes less than an hour if all goes well) then "swap" the node back in. Instead of just adding it back in and re-mirring the volumes, then removing the 2nd node and waiting for it to "un-mirror", you do a swap. Say you have two nodes. You just upgraded node-1. You "Swap" Node-1 with Node-2, this then just copies all data to Node-2. When done, Node-2 can be removed from the management group and then upgraded, then put back in. Then re-RAID all your volumes. <br /><br />I had the advantage of two brand new nodes to work with - that made it much easier and I didn't loss my network RAID fault tolerance.

But in short, I did it, and it worked great. Essentially I purchased two new 6TB SAS nodes, I swapped them in, taking out two older nodes. Then I replaced the hard drives in those nodes to the same 600GB SCSI drives to make those two units 6TB SAS nodes. Then I put those back in, swapping out two other (older) units, and repeated the process. Once all nodes were the same size, the extra space became available. I doubled my space in one cluster, and increased 1/3rd in the other. Then I took my two oldest nodes that I swapped out last, and put 1TB SATA drives in those to make those 12TB SATA units. I then shipped those off to my Disaster Recovery site. They work great also, and are actually much faster than I would have anticipated. It was actually pretty easy. The trickiest part you need to understand is that you need to provide the FEATURE CODE during the re-image process. This can be done via a special file on a USB drive, or you can type it in (but it is LOOOONG) <br /><br />I ended up purchasing my 36 new drives in bulk from a 3rd party for $7,000. It would have been more than double elsewhere. They were the 600GB SCSI drives with the rails. <br /><br />Now I'm sitting pretty with plenty of Terrabytes to spare (for now anyhow).
