The only way to reproduce this is to keep hot plugging drives. To speed it up
once in a while remove the drive before the detection completes.

Hi,
I've got a SATA adapter for a SD card in a Dell Poweredge R610. The BIOS
can see and boot the sdcard, (to Windows, or using syslinux/extlinux), but
when it hands over control to the Linux kernel, the kernel cannot access it.
Here's an excerpt from dmesg:

I've finally bitten the bullet and implemented referrals

TCM now will enable referrals support when an appropriate
map is being fed into 'lba_map'. Format ther

here are some updates to tcm_loop I've done during ALUA testing.

transport failure and added command abort callbacks.
