RE: [gentoo-user] Hotpluggable SATA question...
Wouldn't it have been easier to just google for linux SATA hotplug? The first link takes you to this page: http://linux-ata.org/sata-status.html Which explains that the AHCI hardware supports hotplug, but not the libata core on which the driver is based. So for now, it seems that SATA hotplug is not possible on your system. Thank you, Richard. Actually I had been googling Gentoo SATA hotplug. Best, --Glenn -- Glenn E.

Brett, Will the hotplug package work on these drives? Hmm.

That's the same across all linuxes. If I hotplug a drive into the chassis--it powers up, but Gentoo doesn't see it until reboot. That because it's using the SCSI subsystem in linux. That subsystem was never designed to handle hotpluging. After you add a device to the system, you have to 'echo scsi add-single-device controller bus/chain target/id lun /proc/scsi/scsi'. It is left as an exercise for the reader to detemine the correct values for the 4 variables. Has anyone else used hotpluggable SATA drives in Gentoo 2006.0? Is there some mysterious package I need to emerge for this to work right? From what I understand: There are kernel changes required to get SCSI hotplug (and SATA hotplug) to work hands free. They are in development, but there's no ETA for when they will be supported. -- If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability. -- Gentoo Developer Ciaran McCreesh pgp67wzyRHdV9.pgp Description: PGP signature
Re: [gentoo-user] Hotpluggable SATA question...
I don't know - I figured hotplug would be logical. I'm in the process of replacing a SCSI system with SATA and haven't got there yet.
