SCSI lbolt error

[Rick Garland]

Hi all:

Got HPUX 11.11 on L1000 that is overseas. Getting these messages in syslog.

This is the sctl driver (lsdev 203)

vmunix: SCSI: Target detected parity error -- lbolt: 27723,
dev: cb012002

The ctl devices on the system are /dev/rscsi/c[1-3]t7d0.

What gives?

Thanks

[Luk Vandenbussche]

Rick,

This is the way to calculate it

dev: cb012002

major device number: CB (hex) = 203 (decimal)
controller: 01
target: 2
device: 0

/dev/dsk/c1t2d0 has a problem

[Rick Garland]

HEX cb is 203 decimal. lsdev 203 is the sctl driver.

There is no device c1t2d0 - CLAIMED or UNCLAIMED

System has not been rebooted for 30+ days andthese are recent messages

[Sandman!]

More than likely it is the SCSI controller attached to /dev/dsk/c1t2d0s2 since the major number of the device "cb" points to one. Take a look at the TKB doc below.

Shalom Rick,

Bad disk or a recent hot swap was not followed by a dmesg reset.

dmesg -

Wait 15 minutes

If the message returns its realy a bad disk. A controller or drive cage can cause the same problem and is much harder to diagnose and convince HP hardware what part actually went bad.

Could you post the output of the following:

# ioscan -funC ext_bus
# ioscan -funC ctl

~thanks

[Rick Garland]

Here are the ioscans as requested.
I also did 'ioscan -fn | grep c1t2' and there were no responses.

Whatever is connected to...

ext_bus 1 0/0/1/1 c720 CLAIMED INTERFACE SCSI C896 Ultra Wide

...needs to be looked at. It may just be bad cables or bad/no SCSI termination.

Curious as to what does the following command return:

# ioscan -fnH 0/0/1/1.2.0

~hope it helps

Thanks all
