We are using some 180 GByte Seagate ST1181677LCV and ST1181677LC disks.
The disks with 16 MB Cache are loosing immediately data after writing or some
time later on both partitions (/data22c = dsk38d and /data22e = dsk38e):
vdf /data22c
Filesystem 1024-blocks Used Avail Capacity Mounted on
data22c_dmn#data22c 60078408 58136656 1547680 98% /data22c ( dsk38d )
vdf /data22e_defekt
Filesystem 1024-blocks Used Avail Capacity Mounted on
data22e_dmn#data22e 117148272 30480351 78502016 28% /data22e_defekt ( dsk38e )
here one of the error's:
....

Does anyone have seen this phenomena? Disk replacement (with one disk we have
done this) does not solve this, this phenomena appears again.
I made a disklabel -e dsk38 and a addvol/rmvol to the e-partition on the same
disk one day before. I did not change the partition on which the error occure.
According to this same error's on the e-Partition.

Compaq told - 180 GByte disk are not supported. Actual i did'n got response from
engineering.
Any suggestions are welcome. Thanks, Harald Baumgartner
