Greetings,
I inherited a production F810 some time ago. It has since been replaced with a newer 3020C. During the 810->3020 data migration, I had severe NDMP enumeration latency. NetApp support inquired about various details on the 810, such as the last time it was wafl_ironed, etc. Indeed, the 810 had spun in production for years with minimal admin intervention. Apparently this contributed to the performance hit we took during our data migration.
My question to the list is what are some 'best practices' for caring-and-feeding of a 7.x filer, ala preventative steps to take within OnTAP in order to prevent said problem from happening again in the future. Preferably steps to take on a live filer without interrupting service (impacting read/write/throughput ok, downed filer not).
Much appreciated.
