We want to perform preventive maintenance for our F5 devices quarterly basis. Is there any specific checklist we have to follow other than cpu, memory. Please suggest any standard checklist for PM activity for LTM.
As such there is no documentation available but you can follow few recommendations .
* Always check cpu, memory, process, orphans object etc.and take actions.
* Clear the unwanted file i.e ucs, qkview, asmqkview, .pcap etc. from /var/tmp or wherever you kept it.
* Remove asm audit/history file which is no used.
* Failover active node every Months or alternate months.
* Update signature(ASM), firmware if require.
* add if anything missed.
