I have a PowerEdge 1850 connected to a MD1000 PowerVault. The PowerVault has 15 1TB drives, one HotSpare, with two RAID 5 groups. The server is running Windows Server 2003.
This morning I received the following error message:
"An enclosure management module (EMM) has been removed". The error logs then precede to say that all physical disks have been removed, then a minute later, all disks were "added" again, along with the EMM.
After a reboot of all systems, the Windows server found the drives again.
If this had occurred more than once, one option is to power down the server, move the SAS cable to the other EMM (or swap the 2 EMMs) on the MD1000 and power the server back up. After that monitor to see if the system is stable.

- MD1000 firmware: A04
- PERC5E firmware: 5.2.1-0066
- PERC5E driver: 2.14.0.32 or 64 (32 for x86 and 64 for x64 Windows)
If you're not on these, that would probably be a good first step.
The raid adapter driver and firmware can be found under the Poweredge 1850 downloads in the SAS Raid Controller section ( here).
The MD1000 firmware can be found under the MD1000 downloads under system firmware.
