RPM & SCSI

Allen, we only use SE for all our activities...:( we don't have a license for SMC...

Do you have access to SMC? I have noticed that the most recent version of SMC actually reports on disk speed in the GUI (I'm running v7). I'm not sure when this was introduced, but I'm sure the last version v6.x) didn't do this.

If you don't have SMC, I'm not sure how to get this short of a physical check of your array, and possibly asking for a report from your friendly EMC CE.

I guess that isn't going to work so well then. You should really look into SMC (as a side note). We have ControlCenter, SE, and SMC. At first we tried to do management of our Symms exclusively through ControlCenter. That was too slow, so we switched to command line (SE). Since we started using SMC, we use it most of the time now. The speed of SE with the ease (almost) of ControlCenter. The only thing we don't do in SMC is masking (ControlCenter) and some SRDF & TimeFinder configuration (easier for us on a Command Line).

Not trying to do a sales job or anything, but it really is worth checking out. Of course none of that answers your original questions right now. Hopefully someone else will have some insight into how to do this with SE.

symdev is usually targetted to "logical devices". You need a physical view. symdisk may better answer your question.

You can try guessing RPM from physical drive model.

Or simply ask your CE a list of existing Disk Groups and corresponding RPM speed/drive capacity. You can easily find needed devices filtering symdev "by disk group"

symdev -sid xxx -disk_group  list

Hi Hulk .. I don't have answers for your second question right now ... PER flag puzzles me every time I have to form a meta... I usually forget clearing PER on unused devices and when form new metavolumes I always receive complains from symconfigure since I have a mix of PER-enabled and PER-disabled devices... :-/

Thank you stefano,

Any comments on my second question SCSI?

i tried searching online for drive model, part number ..etc. I could not figure out disk speed. For example disk "FR300LP", i know it's 300G FUJITSU drive but what else ?

Vendor ID : FUJITSU
Product ID : MXW3300FE
Product Revision : FR300LP
Serial ID : DM35A00VP3

You dont need a license for SMC; if you have a Symemtrix its free, there are plug-ins that have costs associated but the base is free. You should be able to download the installer via powerlink.
