 Solution : SCSI bus DATA IN phase parity error
Hi,

I have a HP C1554C DDS2 tape connected to the external glm on a E280R
server.

This is the first time I got this to work; it always crashed between
180mb and 400mb with a "tape read error" and some kernel errors like:

For more information, read about  tape-driver-buffering property in
the st(7d) man page
scsi: [ID 107833 kern.warning] WARNING: /pci@8,700000/scsi@6,1 (glm1):
SCSI bus DATA IN phase parity error

glm: [ID 663555 kern.warning] WARNING:
ID[SUNWpd.glm.parity_check.6010]

scsi: [ID 107833 kern.warning] WARNING: /pci@8,700000/scsi@6,1 (glm1):
Target 4 reducing sync. transfer rate

glm: [ID 923092 kern.warning] WARNING:

scsi: [ID 107833 kern.warning] WARNING: /pci@8,700000/scsi@6,1/st@4,0
(st11):
SCSI transport failed: reason 'tran_err': giving up

This completely failed every time until I removed the SCSI Active
Terminator and just terminated
power to the drive by jumpering the drive.

HP C1554C DDS3 Configuration for Solaris 8 on a E280R

1: TERM Power jumper = on

2: SCSI ID=4

3: 8 switch DIP on drive (Unaltered, using default. I have not looked
at it but I beleive it is the first five on and the last 3 off)

3: No Active Terminator connected to the external tape case ***
Important ***

4: using the glm scsi on a Solaris E280r with defaults ( no glm.conf)

Tar Command to archive and restore

About 3gb from /opt

cd /opt
mt -f /dev/rmt/0 erase
mt -f /dev/rmt rewind

tar -cvf /dev/rmt/0 . 19    

#I incremented down from 20 just for a test but should probably
#work for the default too.

extract:

mount somplace else

cd /mnt
tar -xvf /dev/rmt/0 .
