Sorry for any confusion... I've got several powerpath devices from a dead system that I'm mounting temporarily on one node in my cluster. I run a devfsadm -Cv and vxdctl enable. After that I can see the powerpath devices listed as...
emc_clarrion0_10 auto:none - - online invalid I modified my /etc/vfstab file to mount the devices.. /dev/vx/dmp/emc_clariion0_10s6 /dev/vx/rdmp/emc_clariion0_10s6 /u10 ufs 3 yes - The device mounts and I can access the file system with all my data. When the activity starts to increase on these temporary mount points, I see a count down on the console that port H has lost connectivity. After the 16 seconds, the node panics and of course reboots. However, if I mount the power path devices using a single path.. /dev/dsk/c1t5006016100600432d10s6 /dev/rdsk/c1t5006016100600432d10s6 /u10 ufs 3 yes - I never get the port H losing connectivity. I want to use the dmp name in case I lose a path to these disk. Any reason why using the dmp name causes port H to lose connectivity vs. using a single path?
