In current OpenIndiana (and illumos), predictive failure notices are sent to FMA as error reports. However, there is no consumer of those reports -- they are blissfully ignored :-( Eventually, when the disk really dies, other FMA agents will react, including ZFS sparing, as appropriate. > There have apparently been some firmware issues that produce spurious > warnings, but HP is so Windows centric it's hard to make any sense out of > their support site. > > Is there a Solaris/OI utility for reading the SMART information or doing > other diagnosis? > > The message relates to automatic bad block reallocation.

No. For modern disks, bad block remapping is done by the disk. What you see in format is for very old disks where the sector management was done by the OS. -- richard -- ZFS Performance and Training richard.ell...@richardelling.com +1-760-896-4422 _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
