System Date Rollback: Necessary to Re-Install Solaris
2007-12-25 10:00:00
- Generally no need to re-install as long as the numerous post-dated files
will pose no problems to apps
- Care must be taken on licenses of apps, logfile handling, etc.
- Many suggested doing a 'touch' on postdated files, NULLing the admin log
files /var/adm/*tmpx..
I forgot the name of the person who suggested a 3-way mirror of the
OS/system disk. A very brilliant approach - break the third mirror prior to
date changes, save this disk and work off the two remaining members of the
mirror. Once tests are done, re-attach the saved mirror, devalias to this
disk as the boot disk and boot off this disk, overwrite the other two
members used in tests and re-establish the mirrors.
Thanks a lot!
