Hi. I can't install a patch bundle because /stand/vmunix is not available which is due, in turn, to inability to mount because the device needs fsck. But fsck fails with a media error. Interestingly, reboot works -- it complains about fsck too, though. Is there a way to get fsck to fix this?

fsck is a tool that fixes the structure of a filesystem, things like used and free blocks of data and pointers to inodes. fsck cannot fix bad spots on the disk. The message above means that the data on the disk is unreadable and cannot be repaired. If the disk is not mirrored, you should try to save anything you haven't already backed up and then replace the disk. Reformatting the disk might possibly fix the bad spots with the disk's built-in bad track handler, but once a disk gets a bad spot, it never gets better, only worse. Replace the disk and either restore from the mirror or reinstall HP-UX from your Ignite backup.
