Re: [osol-discuss] Longest uptime?
The company I used to work for had an E450 running Solaris 2.6 and Informix SE plus 4Js that was only ever shutdown for: 1. Power failures longer than half and hour (about every 6 months as we were out in the stix). 2. Changing the battery on the A1000 RAID array, which was required ever 2 years like clockwork. 3. Changing the DDS3 drive every few years as some users were less than sympathetic towards it on occasion. If it wasn't for power outages we would have had 2 years up time - the time between battery replacements. Yes I know it was possible to do this without powering it off, but we weren't that adventurous. ;-) Cheers Andrew.

Re: [osol-discuss] Longest uptime?
Well, we've got several customers (who put out a newspaper every day using their systems, so they do get used) who've had uptime over 500 days. The highest I personally saw was 915ish days. I'd installed the system (e450 w/Sol 6 Sybase 11.0.33) and they just left it alone until I came back to upgrade it. The HA paired system had a RAM module die and only had 600+ days of uptime at that point. See, I tend to agree somewhat (it's like not bathing), but at the same time, there is something to be said for the if it ain't broke, don't fix it crowd. In supporting customers, I'd rather they just leave it alone than try to patch a production system without having a reason. I have to fix systems much more often from human error than I do from just leaving things alone from a sys admin perspective. (Especially when you introduce cluster into the mix).

Re: [osol-discuss] Longest uptime?
Dennis, I think that getting uptime to report 5000 days should be no problem. I wonder what happens if I set the time to a date previous to the epoch? That would sort of force a negative number as the UNIX time. snv_77 will not let you set the time to before 01:00 on the date of the epoch :-( Depends on your timezone, I'm sure.

It's probably a testament to your local power company and your choice of UPS. ;-} I was called by a customer in Quebec that had a very strange situation. I am certain this has happened elsewhere also but on this call I had people in a datacenter asking me ( in french and some english ) how to login to a Sun server. It turns out that the sysadmin that set it up in 2000 left in 20002 and the remaining sysadmin was a pure Windows guy. He was terrified of the Sun server and thus he did everything he could to ignore it or just stay away from it. That Sun server was running production image processing software for the Hospital and I think Siemens was involved somehow. Regardless, the machine had not been logged into as root since 2002 and uptime was well up there in the five year range. A testament to magnificent SCSI disks also. I have data from the SMART firmware on the FCAL and SCSI disks and they were spinning and working non-stop year after year. at least .. until I told them to try a ( L1-A ) STOP-A on the console.
