lsi 2308 raid controller question

Jump to solution

Hi experts

Does anyone have experience with the LSI 2308 raid controller? When I look at my storage adapter in ESX5.5.2 I see it. But when I look at it via cli it says no adapter found:

/dev # /opt/lsi/bin/sas2flash -list

LSI Corporation SAS2 Flash Utility

Version 18.00.0.00 (2013.11.18)

Copyright (c) 2008-2013 LSI Corporation. All rights reserved

        No LSI SAS adapters found! Limited Command Set Available!

        ERROR: Command Not allowed without an adapter!

        ERROR: Couldn't Create Command -list

        Exiting Program.

/dev #

Do I have to load the firmware first to make it work? Like this guy mentioned here? http://www.yellow-bricks.com/2014/04/08/updating-lsi-firmware-esxi-commandline/

I got three SSD that is not being recognized at all by ESX and I am trying to see if the LSI might be what is required to make it work.

Thanks

needed lsi driver update. esx5.5.2 stripped out some of the less common drivers.

Hi,

is that a genuine LSI controller (card) or some OEM (HP, DELL etc.) branded one. Onboard or separate card?

With OEM you have to check vendor's support pages for a firmware updates,

There are several OEM cards and onboard controllers based on the 2308 available, see http://www.servethehome.com/lsi-sas-2308-raid-controller-hba-information-listing/

I'm not sure what you want to do with sas2flash (never needed it, storcli/megacli is much better imho), but it is not worth the effort. This controller is very "low-cost", with limited set of features, and no on-board cache. And as we know (or should know), ESXi does *not* do disk-caching. So if controller without its own cache is used for ESXi-datastore, it delivers terribly low performance...
