Bobbyzsss — Wed, 29 Sep 2010 07:23:32 +0000

I have a permanent spare and dynamic spares are available in the symmetrix array when a disk is going to fail the data available in the failed disk will be copied to permanent or dynamic spare? How the disk choose whether the data has to be copied to permanent or dynamic spare?

Has anyone ever seen a White Paper on the best way to utilize features of both VMWare and EMC Symmetrix based SANs in a real-time or rapid batch based upgrade from SQL Server 2000/2005 to SQL Server 2008 with minimal downtime for application availability?

Tracking DMX storage allocation

SANManJax — Mon, 23 Mar 2009 18:08:42 +0000

How are you tracking your storage allocations from your DMX to your servers? We began with the Excel-based design workbook that EMC delivers at the end of the installation engagement & that works up to a point. I’ve written code that loads the info into SQL & does some reporting on it, but is there a method that anyone uses that does the initial process better? Specifically,
- identifying available devs
- identifying appropriate Tier of storage
- tracking the server reciving the storage
- tracking the FAs the devs are masked to

There’s more, but that’s the core of it.

Thanks for any ideas/suggestions you can provide.

ESX luns allocated on Symmetrix will not format.

Recently we allocated Symmetrix space for an ESX cluster. Some of the LUNs format fine but one or two come up with an error message that says “unable to read partition information from this disk.” All of the luns were exactly the same capacity. The ESX is currently attached to a Symmetrix array as well as a Clariion array.
