I asked:
|Setup: SPARC 10 Model 41, 64M, 6 SCSI devives (3 disks, 2 exabytes, cdrom),
| SunOS 4[.1].3 + bundled patch
|
|When I boot, I get:
|
|Mar 24 11:35:38 inferno vmunix: esp0: Current command timeout [...]
:
|Mar 24 11:35:38 inferno vmunix: sd0: SCSI transport failed [...]
:
|When I'm running, I intermittently get (well ~5 times a day on a lightly
|used machine):
|
|Mar 23 21:46:22 inferno vmunix: esp0: SCSI bus DATA IN phase parity error
:
Net wisdom advised that I check the usual stuff:
* Connectors tight
* Total cable length not too long
* Termination okay (pref with an ACTIVE terminator)
Connectors were fine, Termination seemed okay, but goddamn did I have
some SCSI spaghetti under then desk. 3 of the systems are stacked ontop
of one another but were actually connected with 1m cables. Not having
any short cables free, I simply edited the fstab, disconnected the
chain and rebooted with the internal (sd0) being the only device.
Worked fine, ie it was a cable length problem. Short cables are on
order.
