Only one reply on this one, from Alex Theodore <alex@fuzzycheese.com>, who suggested the T3 cache is being overrun, and that T3's are "notorious for doing this sort of thing." Thanks, Alex. A Sunsolve search turned up the availability of a firmware upgrade for the T3, in the form of Patch 109115 (current rev is -15). This is a flash upgrade that'll have to be performed with the array inactive. -- Tim Evans, TKEvans.com, Inc. | 5 Chestnut Court tkevans@tkevans.com | Owings Mills, MD 21117 http://www.tkevans.com/ | 443-394-3864 http://www.come-here.com/News/ | _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Fri Jan 9 10:00:37 2004
