Cannot access SCSI device
Hi all,
at the oment, I'm struggling with a server containing a SCSI card
(Adaptec ASC-29320ALP) which is connected to an easyRAID. On the
easyRAID, I've created a big RAID6 array which is divided into two
slices. Unformntunately, I didn't succeed in accessing those devices:
# gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.5
Problem opening /dev/sdb for reading! Error is 6.
# ls -l /dev/sdb
brw-rw---T 1 root disk 8, 16 Mar 19 10:36 /dev/sdb
Trying to access /dev/sdc gives the same result.
The server is running Wheezy:
# uname -a
Linux HOSTNAME 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux
"dmesg | grep -i scsi" delivers the followinng output.
(Yes, there is another 3ware SATA RAID controller which works qithout
any problem)

"At time of recovery, card was not paused" seems a little bit odd for
me, but I couldn't find anything helpful yet.
Grepping dmesg's output for "sd*" delivers the following (again;
/dev/sda comes from the 3ware controller):
