Procedure to configure VIO fiber channel, fscsi devices, and virtual disks.

Fiberchannel and fscsi parameters to change (Assumes "fcs" adapters numbered from 0-2):

#!/usr/bin/ksh93

for (( i=0; i<=2; ++i ))
do
  chdev -l fcs${i} -a init_link=pt2pt -P
  chdev -l fscsi${i} -a dyntrk=yes -P
  chdev -l fscsi${i} -a fc_err_recov=fast_fail -P
done

virtual disk parameters to change:

#!/usr/bin/ksh93
################################################################
for (( i=0; i<=15; ++i ))
do
  chdev -l hdisk${i} -a reserve_policy=no_reserve -P
  chdev -l hdisk${i} -a algorithm=round_robin -P
  chdev -l hdisk${i} -a hcheck_interval=20 -P
  chdev -l hdisk${i} -a queue_depth=16 -P
done
