Recently, I found that my E450 is behaving strangely.
1. All backup failed and when I checked the /var/adm/messages I got the following error messages.

Dec 22 14:31:48 webdb1 unix: WARNING: /pci@1f,4000/scsi@2/st@5,0 (st12):

2. All server in my server farm will do a ntpdate every 30 of each hour to some famous time server but only this server have intermittent problem with this ntpdate. Why ??

Anyone shed some light on me ? I will do a SUMMARY at last.
