Delete and Rebuild "Autoraid"

[Ceremony Chap]

Does anyone have any instruction how to rebuild and AUTORAID from scratch ?

I have an AUTORAID model 12L, purchased about 2 years ago. The earliest model of an AUTORAID. I has been working great. Through some training, I discovered that my RAID is not configured for the best performance of my environment. However, since I have not done one, I am kind of shaky to take a chance.

What I am looking for is a step my step instruction., some pitfalls, if there is any.

The RAID has 4MB X 12 HD, with 48MB Cache

Thank,

Ceremony

Hi,

Hope this would help you

12 * 4GB HDD

the get the optimum performance for autoraid its better to leave enough unallocated space for RAID 0/1.

If your HOT SPARE is enabled 4GB will be reserved for that.

the below value's are appox'd

11 GB for raid 5
2 GB for RAID 0/1 controller overhead

effectively you can get 31 GB for data.

In this space you can create the LUN's as per the LV requirement, this can be done through SAM.

SAM - DISKs and FILESYSTEMS

All this info is available in the manual,could be referred for more details

wishing success....

Hi Chap,

Although we are using a 12H model which might be a bit different somewhere, we have basically done what you want to do. We got a 12H with 6x18Gb disk under 1 LUN from HP and reconfigured it to use more LUN's and both disk array controllers for better performance.
Also, I created a log-file and subsequent word-file of the whole process so I could repeat it in the future.
I could mail this to you but have to translate it from Dutch first.
Mail me to mmaanen@computer2000.nl if you're interested.
