[SunHELP] Solaris SCSI weirdness

[Jerry Kemp]

Mark,

If I am understanding your comments correctly, It sounds like to me that you are booting, and everything, specifically including 
drives are working, then at some point, just decide to stop.

Is this correct?

Any error messages, screen captures, etc might assist.

Assuming that you are never getting far enough along in the boot process to log in and look at log files, If I were in your shoes, 
here are a couple of additional things I might try.

1st - from the OBP ok prompt - instead of issuing the "boot" command, instead, do "boot -rv"  . Don't include the double quotes. 
That will do a reconfigure boot, and also boot in verbose mode, and may provide some errors that will aid in trouble shooting.

2nd - Depending on what you have installed, you might also try either a single user mode boot (for pre 10 versions of Solaris), or a 
Failsafe boot, (for Solaris 10 GA and later).  Assuming that this boots, this could allow you to get in and look around for further 
troubleshooting.

Good Luck,

Jerry
