I think it's a BIOS thing. Linux and Windows can't see IDE drives that aren't there at boot time either, and on Solaris the SATA controller runs in some legacy mode so I guess that's why you can't see the newly added drive. Unfortunately all my x2100 hardware is in production and I can't readily retest this to verify. -frank This is exactly the issue; some of the simple SATA drives are used in PATA compatibility mode. The ide driver doesn't know a thing about hot anything, so we would need a proper SATA driver for these chips. Since they work (with the exception of hot *) it is difficult to prioritize this work Disappointing but not completely surprising - "What do you expect, it's an entry level product, not a high end product." Still, would be nice for those of us who bought them. And judging by other posts on this thread it seems just about everyone assumes hotswap "just works". --Toby above getting some other piece of hardware working under Solaris. In addition, switching drivers & bios configs during upgrade is a non-trivial exercise. - Bart -- Bart Smaalders Solaris Kernel Performance [EMAIL PROTECTED] http://blogs.sun.com/barts ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
