Issue on Debian Wheezy with hot-plug SAS hdd

[Кирилл Рудов]

I have HP Proliant DL380 G7 with four SAS hdd on HP SmartArray p410i.
All hdd are configured as RAID-0. I installed on it Debian Wheezy
(linux-image 3.2.0-amd64) without any troubles.
But when I tried to test hot-swap I had an issue. Disconnected disks did
not disappear from system until reboot.

Before switch-off:

meta@ark:~$ lsscsi
[0:0:0:0] storage HP P410i 5.12 -
[0:0:0:1] disk HP LOGICAL VOLUME 5.12 -
[0:0:0:2] disk HP LOGICAL VOLUME 5.12 /dev/sda
[0:0:0:3] disk HP LOGICAL VOLUME 5.12 /dev/sdb
[0:0:0:4] disk HP LOGICAL VOLUME 5.12 /dev/sdc
[1:0:0:0] cd/dvd hp DVD A DS8A5LH 1HE4 /dev/sr0

...and after:
meta@ark:~$ lsscsi
[0:0:0:0] storage HP P410i 5.12 -
[0:0:0:1] disk HP LOGICAL VOLUME 5.12 -
[0:0:0:2] disk HP LOGICAL VOLUME 5.12 /dev/sda
[0:0:0:3] disk HP LOGICAL VOLUME 5.12 /dev/sdb
[0:0:0:4] disk HP LOGICAL VOLUME 5.12 /dev/sdc
[1:0:0:0] cd/dvd hp DVD A DS8A5LH 1HE4 /dev/sr0

 And the system was still running fine after you removed the disk?

Each raid-0 have only one hdd because HP SmartArray p410i don't provide
jbod-mode.

I think I understand what happened.

Sorry for my English :)
