Hello FamousRuler, I would replace the battery in the Perc card first before moving the MD.  You should be able to move the MD & card & should be able to get your MD back online but is not recommended when you have a failed raid battery.  The issue is that the configuration is held on the Perc card & on the drives so you should be able to move & get all backup but have run into issues when have a failed Raid battery that cause the array not to show up after being moved.   Please let us know if you have any other questions.
Hi I have a MD1000 attached to a PowerEdge R610 with a Perc 6/E running a domain joined Windows Server 2008 R2. I need to move the MD1000 to a PowerVault NX with a Perc 5/E running a domain joined Windows Server UDS 2003. The MD1000 only has share files with NTFS permissions. Is it as simple as just power down the servers and attach the MD1000 to the "new" one? Will the files retain the NTFS permissions? Thanks 
Move MD1000 array to another server
