General practices:

>1) Keep air vents and screens clean and clear of blockage

>2) keep a record of internal temperatures, with prtdiag (usually:
/usr/platform/sun4u/sbin/prtdiag), take action to reduce temperature if
>unusual rise in temperature.

> 3) try to keep the computer room below 30 degrees Celsius, 20-25 is
better.

> 4) Configure all ufs file systems with the logging option (Solaris 2.7 and
up). This will install journaling, to prevent file system damage in event
> of system crash, so fsck is not required on reboot.  Example entries from
/etc/vfstab:

> /dev/dsk/c0t0d0s0       /dev/rdsk/c0t0d0s0       /                  ufs
1  no        logging
>/dev/dsk/c0t0d0s7       /dev/rdsk/c0t0d0s7       /usr/local      ufs     2
yes      logging

> 5) Monitor syslog for memory errors, reseat memory boards if the same
error occurs repeatedly. (Use extreme caution, use grounding straps, do
> this only if you are familiar with replacing computer circuit boards.)
This is usually a problem only if the system has been moved or is in a
> high-humidity environment.

> 6) Keep file system usage under 80% for volumes that change frequently
(/var, user homes, databases), under 95% for relatively static volumes.
> This reduces fragmentation and danger of unexpected "file system full"
problems.

> 7) If a large number of files (thousands) are deleted from a directory,
create a new directory, move the remaining files into it, then rename the
> new directory to the old name: this will reduce the size of directories
and improve perfomance.

> 8) Check the operation of CD-ROM drives and floppy drives periodically:
these tend to fail quietly, so they are not available when you most need
> them to reinstall or repair the system.

> 9) Keep keyboards and monitors clean, turn off monitors if not in use.
>
> 10) Test the UPS at least twice a year, replace batteries when indicated.
Do not run a Sun machine without an UPS: conditioned power is necessary to
