Gurus,
I have an M80 with a pair of 6228 FC adapters. One of the adapters is
sending periodic FSCSI_ERR2's accompanied by occasional SC_DISK_ERR4's
from its child "hdisks". The adapters are connected to an F20 ESS via a
SAN. I'm using SDD for path redundancy, and I have a single volume group
which contains two vpaths. Each vpath has six "hdisks", three from each
6228. I need to run diag on the flaky 6228, but I don't want to varyoff
the volume group. Does anyone know if the following procedure will work
as a means of getting the 6228 in a state that'll support diag?
* run "datapath set adapter 1 offline", which will cease SDD I/O
to adapter 1, setting its hdisks' state to "DEAD".
* run "rmdev -l" on the child hdisks and fscsi1 device.
If this works, will the following procedure get everything back to
normal?
* run "cfgmgr -l fcs1".
* run "datapath set adapter 1 online".
TIA,
James Jackson
