Feature suggestion: add support for mpt(x)sas via sas(x)ircu utilities

[edrozenberg]

Hello,

The megacli utility doesn't support controllers using mpt(x)sas (SAS2008, SAS2308, SAS3008, etc).
Instead, these controllers are supported by the LSI sas(x)ircu utilities (sas2ircu, sas3ircu). Perhaps
megamap could make use of these ircu utilities to support more LSI adapters.

The ircu utils can blink drives and do a few other things.

That's a good idea Ed. I'm happy to look into it more.

Before I go buy one of these cards would you mind providing the output of the right sas utility and ls -l /dev/disk/by-id?

Do you know of an easy way programmatically to detect which is installed? Do they use different kernel modules or would lspci output do it?

Hello Christopher,

Please don't buy new hardware on my account or send me your Paypal and I'll contribute :)

Commands output (formatting for LIST is a bit different for sas2ircu vs sas3ircu):

Compared to the generic kernel, I enable these when building in support for mpt sas. Maybe they're not all required:

CONFIG_MEGARAID_SAS=y
CONFIG_SCSI_MPT2SAS=y
CONFIG_SCSI_MPT3SAS=y
CONFIG_FUSION_SAS=y
