The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

How do I add storage to an existing RAID set from second channel, spare, other array or other options?

Asked by scott_hitch in Storage Technology, Computer Servers, Computer Hard Drives

Tags: raid, add, ibm

I have an IBM eSeries 225 running Windows 2000 Server with:
5 - 36GB (34,715MB) SCSI drives (IBM Model: DTN036C1 PartNumber: 06P5323) and 1 70GB (70006MB) SCSI drive (IBM Model: DTN073C1 Part No: 06P5760) on a IBM ServeRAID-5i Controller. All 6 are on Channel 1. They are split into 2 arrays (138860MB) and (70006MB). 4 of the 36GB drives are for the first array and the 70GB drive is the only drive in the second array. The 5th 36GB drive is setup as a hot spare for the first array. Each array is used as one Logical drive (104145MB and 70006MB respectively). The first logical drive is split into C: (13GB/6.3free) and D: (88.6GB/2.44GBfree). The second logical drive is used for E: (68.4GB/43.9GBfree).
My problem is that D: is getting extremely low and the apps that are running there (Doc mgmt, Exchange 5, SQL 7, etc) don't lend themselves to easily moving data around. So what are my best options for getting some additional space? (second channel?, utilize spare?, shrink E: and give to D:...???).
Thanks,
Scott
