So if you're running on a low-RAM system you should take care not to connect too many LUNs to it. As an estimate I would take 1M per LUN; which is grossly exaggerated, of course, but will give you enough leeway to continue with your normal operations.
w/o YaST2, of course, which is a real memory hog :-) Cheers, Hannes -- Dr. Hannes Reinecke zSeries & Storage [email protected] +49 911 74053 688 SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg GF: Markus Rex, HRB 16746 (AG Nürnberg) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
