10.20 Patches with IPL

[Bill Pontius]

When an IPL, due to patches, is required, must it be done now or can it wait for P.M. cron or several days. Also what about both having tape and cd patches requiring an IPL. Must I do 2 IPLs or is there a better way. The new mode of operation is to be here during the day (not night).

Hi,

if you mean that your patches require a system reboot, you could put several patches into one depot to have only one reboot.
From tape:
swcopy -s /dev/rmt/0m @ /tmp/patches
From file:
swcopy -s /tmp/PHCO_XXXX.depot @ /tmp/patches
Then install:
swinstall -s /tmp/patches

Greetings

Andrew

Any EXISTING process will usually run without a problem until completion but any NEW process could run into a real problem where some files associated with one or more patches may be fully installed and others may be staged for installation and configuration after the boot. It's usually a good idea to lock out user access when you do any patching that requires a reboot anyway.
