[SUMMARY-and a rejoinder] :: Slices per disk

While replies are still pouring in let me summarize, as all are in agreement that it is not possible to do this in Sparc although intel (x86) allows upto 16 slices. Under sparc the Veritas Volume manager allows one to create more than 7slices although it does not use the actual slices to do this. How Veritas does it exactly was not clear to me.

One respondent wanted to know WHY I should be interested to do this. Well, maybe I should have mentioned the Why of it in the first place, but I thought that there could be a way to do it. Here's why:

I have 3 disks each 9Gb. I have 3 slices of 3Gb on each disk. I am using them as a normal ufs mounted file system. To improve data retrieval I intend to do striping using SDS. But I want to maintain the size to 3 Gb per metadevice and sripe across the 3 disk. For this I find that I have to have 9 slices of 1Gb each on each of the disk. In other words, I want to convert 9 slices of 3Gb/slice to 9metadevice of 3Gb/metadevice. From all the response received so far, it looks like I have to move over to Veritas. Any other ideas are still welcome and I will summarize again.

My original post:

This may sound silly but is it possible to create more than 8 slices (s0 - s7) per disk? If so, how could this be accomplished. Thanks in advance for any help.
