On some Intel servers a glitch with the RAID Copyback feature can cause the RAID Card to continue to beep even after a failed drive has been replaced. The system may start beeping again when the system is rebooted.
The Intel RS2BL040 and RS2BL080 are 4 and 8 port controllers based on the LSI 2108 first generation 6G SAS chipset, and are Intel's branded version of the LSI 9260-4i and 9260-8i respectively. These cards have shipped in large numbers of Stone servers since 2012 to 2016. There is a wide variety of firmware versions in use in the field. During the card's life, new features have been added by Intel including the Copyback feature.
Problems with the Copyback Feature
The Copyback feature is designed to rebuild back onto the original drive slot after a RAID repair to a hot-spare has been completed. For example:
State after drive failure:
With Copyback, the idea is that when you replace the failed drive in Slot 1, that the system rebuilds onto Slot 1, and Slot 2 reverts to being the hot-spare drive.
In some versions of Copyback, notably with firmware version 0104, when you replace a failed drive in a system that does not have a hot-spare, the act of marking a new drive as a hot-spare to begin the rebuild process leaves the system requesting a second rebuild after, to complete Copyback.
To avoid a copyback issue on the RS2BL040 or RS2BL080 with firmware version 0104, either change the RAID card properties so that it automatically rebuilds, disable Copyback, or upgrade the Controller firmware before replacing the drive.
To Set Automatic Rebuilds On
You will need the Command line utility Storcli. This can be used inside EFI or a Windows environment. Use the commands below to list the controllers and get the right controller number, i.e. 0 or 1. For example, you may have an onboard ESRT2 controller - usually controller 0 - and an add-in RAID module or controller, usually controller 1.
To show the existing auto-rebuilld setting:
storcli /c0 show autorebuild
To enable auto rebuild on controller 0:
storcli /c0 set autorebuild=on
To Disable Copyback
Again, you will need the Command line utility Storcli. This can be used inside EFI or a Windows environment. To disable Copyback on controller 0:
storcli /c0 set copyback=off type=all
Tip: On this model of RAID card it is not possible to set the Autorebuild or Copyback features from the RAID BIOS. It is also not possible to set this using RAID Web Console.
To Check That Copyback is Disabled
Run the command below:
storcli /c0 show copyback
To Upgrade the Firmware
See the attached article.
First, download the RAID TTY log using RAID Web Console to confirm the cause of your issue. If Copyback is the cause you of your problem, you will need to either:
