Upgrading RAID5 hard drives

By Piks ·
I am running a Compaq Proliant 2000 with a seven hard drive array. The hard drives are 1.9GB upgraded to 4.3 GB. The EISA configuration sees the new hard drives as 4.3GB. The RAID Smart Controller sees the drives as 4.3GB.
How do I expand the Netware partitions to take advantage of the additional storage space? I have tried to add segments to the volumes, but Netware says that, "there is no free area to add." If I try to create a new volume, Netware tells me again that, "there is no free areaavailable to create a volume." Do I have to remove the partitions, re-create them to a larger size and than restore the backup? Thanks for your help in advance.

Upgrading RAID5 hard drives

New disk drive space put into an array is not available for use. What you have now is replaced SCSI drives with "at least enough space for the present RAID config." Thus, they are only allowing the same system drive size as the original. You NEED tomake the array into a new system drive using the full size of the new disks.

Optionally, you can go into the array manager on boot; create another RAID system drive and then reboot into NetWare; create a new NW partition area; then add a new volume on the newly created system drive.
[*Or (I don't think this will really work) you can hope to expand an existing volume using the new partition - not in NW 3.x, only maybe in 4.x and if using NW 5 with NSS for the desired volume good shot. If the NSS option is tried, you'd have to have the present volume already online as an NSS volume.]

Your options are: 1. load the array manager then add a new drive. 2. (The right way) get 2 (two) good backups, then go back into the RAID config on boot. Reconfigure your array for the new drive sizes. Then restore the tape. At this point, you can probably just expand the volume(s) you want and go on your way.

Upgrading RAID5 hard drives

The project was simple. Upgrade a Compaq Proliant 2000 server's hard drives with a seven drive array configuration. This server was manufactured in 1994 and put into service in June, 1995. After submitting this question to Techrepublic, I called Compaq. To my surprize, they refused to help in this case because the server is, "too old". I called Smart Start, and they could not even tell me what version of smart Start to use, let alone point me towards a copy that I can buy, download, or steal. This project spanned four weeks and has a total of 245 man hours. Therefore, let me impress upon everyone that a "RunTime" book FOR EACH server is absolutely essential.

You need indeed to expand your RAID, or add a "virtual disk" to your RAID set. Given the "age" of your Proliant, I doubt if there is a recent enough SMART controller in there to allow on-line expansion and so, so prepare for some off-line tasks.
-Download "ACU" (Array Configuration Utility) from Compaq.com, and install it. You may need to do this from the System Partition, or if that doesn't exist, you may need to boot Disagnostics, and select the Array Configuration there, it will ask you to insert the diskettes.
-Depending on what RAID controller you exactly have, you may be able to expand a RAID set (which I doubt), or create a new virtual disk in an existing RAID set (this may take hours), or create a new RAID set (this will go quickly). The difference is that a second virtual disk takes the RAID-fault tolerance of the existing set, and a new set will require you to start all over. In other words, it's most likely a choice between a slow expansion, or giving up some disk space, since the new set will have its own "parity" disk.
-Boot, start NetWare
-Now it depends on your NetWare version, and I suppose you know how to create a partition using either INSTALL.NLM or NWCONFIG.NLM.
-If you have NW5 and NSS volumes, don't create a partition, but assign the new empty space to NSS, and expand existing volumes, or create a new one.
-If you use traditional volumes, you can choose between adding the empty space on the new partition to (an) exisiting volume(s), or to a new one.

-Watch out when creating partitions: only NW5 can handle more than one netware partition per disk, and more than 4 partitions per disk. A disk in this case is a "virtual disk" created in your RAID-set.
-Please, please, make very sure you have a good backup. All it takes is a brownout when expanding your RAID...

I have already installed ACU from Compaq. Evidently, I have a very old Smart Controller, and I'm using NW3.12.
Thanks for the help!

Look at Server Magic. The same maker of Partition Magic. It says in there ads it can do what you want.

I cannot see paying $500.00 for a work around. But I can see, where in certain circumstances, you have no other choice. In my specific case, I was able to generate other options.

Thanks,

Hi Kenneth,
Be prepared for a large night...
Unplugging the 1.9 HD and plugging the 4.3 will keep the array working but with 1.9MB (controller-made) partition size.
There's nothing that you can do because if you create another partition on HD, Netware will respond with "a netware partition already exist on this disk"
Only New controllers eg: CPQ-5300 are able to extend ARRAY partitions on the fly.

Good luck!

I agree with you assessment. A new controller would be the answer. Especially when Compaq refuses to help you because the server is, "too old". However, since our merger with Nation's Bank, the technical dollars for maintaining and upgrading thehardware is no longer available.

Thanks,
Ken
