Shalom,

Bad disk.

May 23 16:01:21 HP_UXserver1 vmunix: lbolt_at_timeout: 877578080, lbo

Few possible causes:
1) Someone swapped out a hot swap disk.
2) A disk was really busy and exceeded timeout.
3) A disk stopped working.

Item 1 can be ignored and will go away next boot. Item 2 may indicate a hotspot and an i/o problem in need of address. Item 3 may indicate a dead disk based on the hardware information posted to this thread.

Hi,

Try:

# diskinfo disk /dev/rdsk/c0t8d0

SEP is right, if the error still exist after some times for only this address then you will have to replace the disk. If it happens for other disk, then you must look into I/O issue or cables etc.

May i know what type of disk you are using?

Regards,
Sandy
