I have HP Proliant DL380 G7 with four SAS hdd on HP SmartArray p410i.
All hdd are configured as RAID-0.
Wait.. unless I'm missing something, raid-0 will no prevent for data loss
when you remove one of the disks regardless their hot-swapping
capabilities :-o
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.
And the system was still running fine after you removed the disk? Wow, I
wonder what dmesg was saying...
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
If you are using the stock hpsa driver I'd take a look at the docs:
