Greetings.
I'm brand-spankin' new to this list, so please please please excuse me if I landed this question in the wrong space/time.
It's an appropriate question for the list.
I'm looking for infomation on NetApps because the company I'm working for is considering a 760 for our network.
Cool. It's a nice box. I like it.
I have been told by someone who is only vaguely familiar with the NetApps that the filesystem has to be maintained in some way by running a _wac_ command,
There are commands, like "wack", that are available to be run in certain modes. They are not part of regular maintenance. They are used if the system has suffered some horrible calamity, like a double disk failure, or single failure combined with extrordinarily stupid user behavior, such as removing a disk and destroying it while the system is rebuilding another failed disk. The circumstances under which these commands need to be run are rare, and under all circumstances, not normal.
but I have been unable to find any information on such a command in a week of searching . Can anyone fill me in on the use of this _wac_ command , what it does, how often it needs to be done, and whehter or not the filer requires downtime to do it?
On most systems, it never needs to be done. If it does need to be done, the system would be offline. It make take a great deal of time for the command to complete. I have had to do this, myself, maybe 3 times in my 5 years of working with NetApps, and those were a long time ago and during times when the filers were working under, uh, strenuous circumstances.
Short answer: Don't worry about it.
