These problems were fixed by earlier RTI 1163511 (patch T102002-02). However, there is a simple additional change required for fixing reset related problems in the esp driver. This RTI is for updating the patch with this additional fix. (from 102002-02) 1163511 esp: bus device reset may result in not completing some requests On high availability systems (HA), the sd driver may issue many scsi bus and bus device resets. Usually, this works but sometimes this causes loss of packets, hangs, or panics. Similar problems occur during scsi abort''s. The fix for this is extensive (ie. the entire reset/abort handling had to be rewritten since it was fatally flawed). Code in the critical path is also affected. (from 102002-01) 1173973 esp: scsi resets occurring more often with newer fab FAS286 chips On Sun4d systems (both sundragons and scorpions) we are getting more scsi timeout resets now with the newer reduce die FAS286 chips ( 2400150). They are no longer making the old style chip (2400121) anymore . It doesn''t seem to be configuration dependent. On sundragons it occurs most often on tape devices. It also shows up more often with the 1/2 height exabyte 8 mm tape drive.
