What server is this and which scsi bus do these occur? It is scsi bus c4 but what kind of devices are they? internal disks, external, enclosure type etc.
The explanation for each condition is the same generic error that we see all the time. Other than what I said earlier about them being bogus and caused by EMS/STM, there may be actual scsi bus resets on the c4 scsi bus and these resets are caused by a variety of reasons.
1. A flaky scsi controller in the server, or an interface on an external enclosure, or a scsi cable or a terminator or one of the disks. It is unlikely that all the disks are failing intermitently.
2. Intense i/o traffic on that particular scsi bus. If this is the case you may be needing some scsi patches.
3. You manually interrupt the bus by disconnecting a cable or the terminator and attach or disconnect another device such as a tape drive or a disk or a CD/DVD drive.
