Hi Josh, Thanks for getting back to me. The physical connections to the drives were good and they were showing up in the RAID config of the updated controller. But the Virtual RAID1 drive had disappeared. I solved the problem by downgrading to an earlier firmware version. If I had read the README of the first firmware upgrade page completely, I would have noticed: Migration of RAID Volumes from SAS 6/iR controllers to PERC6 controllers is supported only for volumes originally created on SAS 6/iR controllers running FW revision 00.25.47.00 or later.I was able to locate a FW version 00.20.48 here. The flash.bat executable refused to downgrade the FW version :emotion-7: However, looking at the .bat files, I could see that flash.bat called xflash.bat which called sasflash.exe which is an LSI utility to update the card firmware. I found an old manual with the arguments that sasflash.exe take here and used the -fwdown switch to wipe the card and downgrade the firmware. When the server booted back up the virtual drive was back. Phew! Guess I will read the README next time? Thanks for you attention, Jerry.
Hello, We have a Dell T300 with the SAS 6/iR adapter. We have a RAID1 with 2 x 3TB drives (only 2TB visible). I updated the firmware on the SAS adapter to the latest version available here: [URL] and now the RAID 1 has disappeared!!! We have a lot of important data on this virtual disk so any help would be much appreciated. Thanks! Jerry.
