Removing drive tray from Clarion array

[Kevin M. Myer]

Hello,

This is slightly off-topic, but I'd like to know if anyone has had a 
good experience removing a drive tray from an EMC Clarion array.  
There's plenty of documentation for how to add a tray to a Clarion 
array, but I can't find any about removing one.  I guess everyone 
assumes that storage needs will only continue to expand :)

Here's the situation:  we have two CX300 arrays.  Each obviously has 
the base tray, with the SPs.  The array at our primary site also has a 
DAE-ATA tray.  We've purchased an additonal DAE2-ATA tray, with the 
7200RPM SATA drives.  Since this should yield slightly better 
performance than the existing ATA tray, and it has higher capacity, I'd 
like to install the new ATA drive in the primary array, migrate the 
LUNs from the old ATA tray and then remove the old ATA tray altogether 
and add it to the fabric of our secondary array.

I'm fine with getting the new tray hooked up, data migrated etc.  But 
what happens to the primary array when it boots up and a tray it used 
to have is no longer available?  Will it proceed merrily on its way and 
not even miss it, or will it constantly be complaining about a missing 
tray?

Thanks,
Kevin
