My system is not detected anymore the raid controller.
The red led is blinking on the card (CRT5a2 Led)
I changed the PCI card location and i did a reset to bios but nothing happened
i guess that you are on wrong forum.
CRT5a2 is related to LSI 3ware product. This is a forum for Brocade SAN fibre channel products and solutions.
I think your question has been posted to the wrong forum.
following the correct answer.
LSI bought years ago 3Ware. later If I rememebr correct 2014 ? LSI was acquired by AKA AVAGO today Broadcom Inc.
anyway, this Controller is around 10 Years old, and not longer supported neither by AVAGO nor any other Vendor.
Typically, a red LED blinking indicates a device failure.
I would recommend reviewing POST startup to see what messages are displayed. Most likely, you will need to replace this card.
