Solaris

any one can help me. my system running on solaris 2.7. recently there is sudden power failure while system running. after that unable to boot the system. it is giving comment that "can not open /etc/path_to_inst" and then returning back to "OK" after comment of termination. The processor is USPIIi

I think some booting process software has been corrupted. Is there any method to recover the disk without formatting. I am having the CD Rom of solaris 2.7.
Pl help.

try a "boot -rsv" and look for errors.

boot -ar

yes, but only after the first boot to see if there are filesystem errors... the "-a" option creates a new /etc/path_to_inst but if there are problems with the filesystem they need to be fixed first...

what do you think?

How would fsck open /dev/rdsk/c0t0d0s0 if path_to_inst is missing? The kernel needs something to populate /devices. I'm not sure if an initial fsck is an option unless you boot from cdrom to do the fsck. But I have never tried it.

i didn't want to run fsck... the "boot -rsv" was for having a closer look at the problem... for an fsck you clearly need to boot from cd or network.

No, I meant what I said..."boot -ar". If the root filesystem needs an fsck it won't come up beyond single user mode and it won't be able to create the path_to_inst.


In that case the -r and -s are redundant. The system is not booting so -s makes no difference, it's not even getting as for as single user and the -r wouldn't be any use in the case either, in fact it simply won't work without the -a for the reasons given by Perderabo.
