It is my understanding that MD/DM does not have the specific commands to support controller failover in the EVA. -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Luca Berra Sent: Monday, September 20, 2004 11:34 PM To: linux-raid@xxxxxxxxxxxxxxx Subject: Re: SuSE Linux cluster using MC/ServiceGuard --- shared storage On Mon, Sep 20, 2004 at 08:33:18PM +0200, Lars Marowsky-Bree wrote: >On 2004-09-20T15:55:51, > Luca Berra <bluca@xxxxxxxxxx> said: > >> >Do I still need to use the Driver Patch for EVA >> >Controller Failover? >> i believe using the qlogic driver failover is a viable solutio, > >The DM multipath in 2.6 should handle the EVA just fine. you mean multipath-tools (http://christophe.varoqui.free.fr/multipath.html)? i suppose so, using the "group_by_tur" spreading policy. fortunately i don't have any spare EVA to test, plenty of XP tough :) >The qlogic internal failover is being depreciated and AFAIK isn't >included in 2.6 mainline even... excuse me, are you shipping (or at least supporting) a 2.6 kernel on your SLES 8.0 product? >> another is purchasing securepath from HP. but i believe there were >> issues using securepath and lvm together. > >Proprietary multipathing solutions are a thing of the past on Linux, one >hopes. i hope so, but for this statement to become true we need some other vendor to ship a 2.6 based 'enterprise level' distribution with proper device-mapper implementation, and application vendors (that includes HP and IBM) to adapt. Anyway, i do not really believe securepath to be a viable solution(*), i was enumerating possibilities. (*) and hp suggests using qlogic 7.00.3 driver with internal failover for use with their Serviceguard product. -- Luca Berra -- bluca@xxxxxxxxxx Communication Media & Services S.r.l. /"\ \ / ASCII RIBBON CAMPAIGN X AGAINST HTML MAIL / \ - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
