Hi,
1. make sure device tree is clean, and disk is ok:
#devfsadm –Cv
use dd read to test if disk is ok:
# dd if=/dev/rdsk/c1t2d0s2 of=/dev/null bs=1024k count=100
2. get prtvtoc for the disk:
# prtvtoc /dev/rdsk/c1t2d0s2
3.make sure the disk is proper labled.
# cfgadm –alo show_FCP_dev
# echo label > /tmp/fmt ; format –d c#t#d# -s –f /tmp/fmt << Label the LUN ( c#t#d# ) prior to updating VxVM
4.refer http://www.symantec.com/docs/TECH57018
freeze vcs sg,
# mv disk.info disk.backup
# mv array.info array.backup
# rm /dev/vx/dmp/*
# rm /dev/vx/rdmp/*
#rm /dev/dsk/c#t#d#s# <------Remove all entries except for internal boot devices.
