Solved!
Go to SolutionDetermine drive speed from ECC or SYMCLI?
Looking at a new environment does anyone know how to query a Symmetrix (or Clariion) to determine the speeds of the physical drives in the system?
I know some of the part numbers off-hand, but for older (or brand new) systems it is hard to keep track of the exact part numbers. Does anyone know a query to confirm that a Seagate CUDA180 is a 7200k drive instead of having to hit Google and hope you can find a description match?
Yes I know you could go and check the PO, that is cheating, looking for a technical answer if there is one.
Thanks.

That solution looks like exactly what I want - but unfortunately we are not to Control Center 6.0 yet.
Does anyone know of a way to do this with SYMCLI or some other non Control Center 6.0 method?1009

AFAIK the speed of an HDA is invisible from the host (neither via symcli nor via ECC) .. I think that what ECC 6.0 does is simply to associate the "description" of each HDA (you can have them via the "symdisk list" and "symdisk show" commands) to the speed of the disk via some kind of table that's inside ECC 6.0 (and was not available soon).
BTW here's the output of the "symdisk list" and "symdisk show" commands.

I was kind of hoping someone would say they already had a cheat sheet or an EMC document showing all the different drive numbers1009

Unfortunatly I don't have such a cheat sheet .. But you can install ECC 6.0, find the Oracle table that have the informations, dump it into a file, uninstall ECC 6.0 and live happy
I'm sorry but I don't have ECC 6.0 ..1009

Hi Bodnarg,
You can always have a quick word to your local friendly EMC Customer Engineer. They can provide all of this information directly from the Symmetrix bin file. Otherwise your local CE can provide a copy of the file drives.txt from the Symmetrix Service Processor. It is in the SymmWin, ConfigWizard directory and contains a list of the latest drive models, part number, size & speed. Once you determine the installed drive models through SYMCLI commands this "cheat sheet" should give you the rest
Best Regards,
Michael.1009

Hmmm I think that installing ECC 6.0, dumping the table and then uninstalling ECC 6.0 is a better wayehehehe
I knew that there was something in the SP that told SymWin the different types of drives .. But I'm not a SymWin expert at all !!
Nice to know that there is a "drives.txt" file !!!

That's exactly what I always do: call my friendly local CE friend and ask him to produce an overview of disk groups and device number we're using. These 2 sheets will show the drive speeds as well.
Anyone noticed that the 7200 rpm drives will show up as 7500 rpm drives ?1009

Hi RRR,
Just F.Y.I.
It's a documentation error
The LC Fibre Drives ARE actually 7200 RPM as per the EMC Sales literature but the SymmWin program has them listed at 7500 RPM. I will see about getting that corrected....

Thanks, I've asked my friendly local CE tons of times about this, but all he could say was "I dunno, don't worry 'bout it".
Oh well, if 7k2 will be mentioned, that would be acurate indeed !

Please refer to primus emc167756 "How to tell the disk speed of a disk on a Symmetrix array that supports a device in ControlCenter 6.0".
