Sun Cluster: boot disk encapsulation

Posted in Sun Cluster at 3:02 pm by alessiodini

today i have encapsulated a boot disk on follow environment:

– Solaris 10
– VxVM 4.1
– Sun Cluster 3.1u4
– Hitachi Storage

After read checklist , i have done some test on rpc services , heartbeat , name resolution , vxvm.
Follow some detail of boot:

# scvxinstall -e

Disabling DMP.
scvxinstall: /dev/vx/dmp is not set up correctly.
scvxinstall: Warning: Unable to disable DMP, but installation will continue…
scvxinstall: /dev/vx/rdmp is not set up correctly.
scvxinstall: Warning: Unable to disable DMP, but installation will continue…
The Volume Manager package installation is already complete.
Discovered and using the predefined vxio number 235…
Volume Manager installation is complete.
Verifying encapsulation requirements.

The Volume Manager root disk encapsulation step will begin in 20 seconds.
Type Ctrl-C to abort ………………..
Arranging for Volume Manager encapsulation of the root disk.
Reinitialized the volboot file…
The setup to encapsulate rootdisk is complete…
The /etc/vfstab file already includes the necessary updates.

This node will be re-booted in 20 seconds.
Type Ctrl-C to abort ………………..

After a couple of boots i have seen:
