Hi All, I have Solaris 10 running on Dual Xeon, The last time it had patches installed was March 2005. I installed all patches from March onwards this morning, and now the machine will not boot. I had RAID1 mirroring setup on the machine, and all it does now is complain about an "Unrecoverable read error" on c2d0s0 the 2nd disk. The machine never boots. If i disable the 2nd Disk in the DELL Bios, i get a kernel panic and a boot loop. Also,if i boot with the install CD i can't mount the root drive using mount /dev/dsk/c1d0s0, it tells me that its an invalid boot device. Both these drives were fine this morning, so i expect one of the patches has corrupted something. If i could get into the console, i could delete the replicas and just disconnect the 2nd drive from the configuration. Any ideas how i can get into the console on this box? The console i have (boot interpreter) only allows me to do 1 or 2 things, no mv, rm,metadb, nothing! NOTE: i was able to get in and mount / by letting the CDROM installer get pretty far and then cancelling, but it is a "read only file system" so i can't change anything.. help! Mike
