|
|
I have a server with something called "PERC H710 Adapter RAID Controller", which (I believe) is a hardware RAID interface. I went into the BIOS screen and set it up as RAID-5, and I didn't use LVM.
Is there a way to find out whether one of the disks has gone bad? When something goes wrong, the lights on the disks change from green to orange, but the server is currently stored in the server room, so I can't keep my eyes on it. I contacted the server vendor but there was no help, because Gentoo isn't an OS they support. I'd appreciate any suggestions.

I've always been able to find a utilities package for every hardware RAID controller I've used. The utility outputs status and, when run from a script launched by a cron job, can make a decision to email me if there's an issue. Works like a charm.

I don't believe that SMART and hardware RAID status are the same thing.

The PERC H200 controller will let you query the SMART status directly with smartctl. IIRC, you should have /dev/sg\d+ devices for each drive which you can query, each one maps to one of the underlying drives. I would assume the H710 is similar. _________________ Game! - Where the stick is mightier than the sword! |

I finally got around trying out "smartctl", but unfortunately, it doesn't seem to be compatible with what I have.

Yeah, like I said, SMART != RAID management. A little Googling determined that the package for Perc RAID controllers is Dell OpenManage. There's a Debian package here, so you'll have some work setting it up under Gentoo. I wasn't able to find any existing ebuild.

Smart as nothing to do with managing raid. You need a raid managing tools.
And because the raid array is not a disk, smartctrl fail on it. But your raid tools should provide smart capability. |

Do you have any /dev/sg* devices? See my post above. _________________ Game! - Where the stick is mightier than the sword! |

There are a few /dev/sg*, but again, I think I'm looking at the wrong direction.
Code: | $ ls -l /dev/sg*
crw-rw---- 1 root cdrom 21, 0 2012-08-30 09:36 /dev/sg0
crw-rw---- 1 root root 21, 1 2012-08-30 09:36 /dev/sg1
crw-rw---- 1 root disk 21, 2 2012-08-30 09:36 /dev/sg2
# sudo smartctl -i /dev/sg1

As mentioned by JRG, Dell's OpenManage Server Administrator looks promising, but the Dell support wasn't exactly helpful, because I'm not using the Linux distro they are supporting. I'll do some more digging and report the progress.

I wouldn't've expected any help from Dell. I didn't get any help from Adaptec either but there is an ebuild for their older controllers in Portage (sys-apps/raidutils) which I've helped maintain. krinn's right about the newer ones: I made an (as yet unsubmitted) ebuild for arcconf which supports their newer cards. Both work very well under Gentoo.
