Hi Valeri, Before you pull a drive you should check to make sure that doing so won't kill the whole array. MegaCli can help you prevent a storage disaster and can let you have more insight into your RAID and the status of the virtual disks and the disks than make up each array. MegaCli will let you see the health and status of each drive. Does it have media errors, is it in predictive failure mode, what firmwa...

Triple Release Day! James Wan, from the Solaris Quality Engineering group, has released the Megacli test suite.

Anyone > know of one, or is what I want to do rebuild the RAID? I agree with what John said about their command line interface MegaCli. One thing I have noticed about LSI MegaRaids is: if you hot replace bad drive with good one of the same size or larger (which doesn't have on it traces of being configured in any raid, not necessarily LSI), then the drive is accepted as replacement member into the same volume group, and array...

Got a new box I'm trying to set up. I configured the RAID from the firmware, but "fast initialize" was sitting there at 0% (it's about 43 or 45TB). The first time I tried this, I said background, and rebooted the system. And the stupid annoying alarm started up as the system came up. This time, having *finally* figured out how to set up hot spares from the WebBIOS, I suspended

...chatting with LSI/Avago/Broadcom and one completely fruitless round of chatting with HP, I found confirmation under the storage section here: http://www8.hp.com/us/en/mpc/workstations/product-detail.html?oid=5225041#!tab=specs It looks like HP didn't "request" MegaRAID support, so MegaCli and StorCli don't see anything and neither does lsiutils (nor hpacucli, tried just for a laugh). Any clues appreciated. Thanks for your time. Cheers, Zube

I am having an issue with Megacli when adding or removing virtual disks. I will post a link to fpaste that has the issue shown. In brief whenever i add, or remove, a virtual disk via MegaCli the attempt succeeds and the adapter is configured but the OS remounts dm-0 in read only. dm-0 is my root lv. This issue does not happe...

...using an LSI MegaRAID experienced "disappearing drives"...? We installed 6 new C6 servers, each with a Supermicro SMC2108 (LSI MegaRAID) controllers and 3 PX-128M5Pro SSDs ( RAID1 + hostswap). 2 weeks (and almost no activity on it, since not in production, apart from installation) later, megacli sees (based on the slot numbers): - on one server: only the 2nd disk of the RAID + the ex-hotswap brought online. NO sign of the first disk, no error message, it just "disapeared"... - on another server: apparently lost 1 of the 2 RAID1 disks and then the second disk of the RAID1...? Now...

i'm configuring a storage server with CentOS 6.2, it uses a LSI MegaRAID SAS controller, I'm using LSI's megacli to configure the storage... Any ideas on how to get drive failure notifications out of this system? I'm configuring hot spares but I'd still like some sort of notification when a drive has failed so the spare can be replaced. -- john r pierce N 37, W 122...

...its flashed with IR firmware... this only supports raid 0/1/10. I always(!) flash these with the IT firmware that turns them back into a plain SAS HBA, and then use operating system native raid (mdraid for centos). the megaraid management software does support these chips in IR mode, but megacli is an awful thing to use. i found it so awful that I located and tweaked a couple python scripts to make it easier to use on a LSI MegaRAID 9261-8i (which doesn't /have/ any IT mode) # lsi-raidinfo -- Controllers -- -- ID | Model c0 | LSI MegaRAID SAS 9261-8i -- Volumes -- -- ID | Type |...

We're looking for tools to be used in monitoring the PERC H800 arrays on a set of database servers running CentOS 5.5. We've installed most of the OMSA (Dell monitoring) suite. Our current alerting is happening through SNMP, though it's a bit hit or miss (we apparently missed a couple of earlier predictive failure alerts on one drive). OMSA conflicts with mega-cli, though we may

I just had an IBM in a remote location with a hardware raid1 have both drives go bad. With local machines I probably would have caught it from the drive light before the 2nd one died... What is the state of the art in linux software monitoring for this? Long ago when that box was set up I think the best I could have done was a Java GUI tool that IBM had for their servers - and that seemed like
