How to run sundiag on multiple cell nodes - exadata or SSC:
What is sundiag:
sundiag is Oracle Exadata Database Machine - Diagnostics Collection Tool which collects diagnostics information which help the support analyst in diagnosing problem such as failed hardware like a failed disk, etc.
In Exadata box or solaris supercluster (SSC) we may have multiple storage cell nodes attached.
If we have 10-12 storage cells nodes then instead of login to each and every cells and collecting sundiag will be a time consuming task. By below one command we can run sundiag on multiple servers (passwordless ssh should be there from the compute node to the cell nodes).
1. on Solaris super cluster:
#dcli -g /opt/oracle.supercluster/bin/cell_group -l root /opt/oracle.SupportTools/sundiag.sh
where # cat /opt/oracle.supercluster/bin/cell_group --> will list number of cell nodes attached to the SSC machine
2. on Exadata servers:
#dcli -g /opt/oracle.SupportTools/onecommand/cell_group -l root /opt/oracle.SupportTools/sundiag.sh
where # cat /opt/oracle.SupportTools/onecommand/cell_group --> will list number of cell nodes attached to the Exadata machine
