Hitachi Storage Cluster (HSC) Data Collection

Timeline of events

Example:
- HSC script times out on node A 
- Node A failover to node B
- Server running node A reboot
- Node B fail back to node A

Host Information

Windows GetConfig for Hyper-V
VMware Diagnostics

Collect all event logs from the server event logs around the time of failure (system and application)

• %SYSTEMROOT%\system32\config.

Config files

Collect the HSC Config Files and a copy of the script

• %SYSTEMROOT%\*.conf (where * is the resource name of HSC in the cluster).

Cluster logs

Obtain the cluster logs from the previous owning node and the failover node. This log is located on each node.

• C:\%SYSTEMROOT%\cluster\cluster.log.

Pair Displays

From the CCI executable directory (usually C:\HORCM\etc), review the current pair status of the cluster volumes. From both the previous owning node and the failover node, run:

• pairdisplay -g -CLI -fc

Use -l if the remote node is not available. Collect screenshots from the output of the above commands.
