5.5 HP StorageWorks X9720 Network Storage System Administrator Guide (AW549-96026, March 2011)

NOTE:
During the X9000 Software installation, the names of crash dumps in the /var/crash directory
change to include _PROCESSED. For example, 2010-03-08-10:09 changes to
2010-03-08-10:09_PROCESSED.
NOTE:
Be sure to monitor the /var/crash directory and remove any unneeded processed crash dumps.
Configuring shared ssh keys
To configure one-way shared ssh keys on the cluster, complete the following steps:
1. On the management console, run the following commands as root:
# mkdir -p $HOME/.ssh
# chmod 0700 $HOME/.ssh
# ssh-keygen -t dsa -f $HOME/.ssh/id_dsa -P ''
This command creates two files: $HOME/.ssh/id_dsa (private key) and $HOME/.ssh/
id_dsa.pub (public key).
2. On the management console, run the following command for each file serving node:
# ssh-copy-id -i $HOME/.ssh/id_dsa.pub server
3. On the Management Console, test the results by using the ssh command to connect to each file
serving node:
# ssh {hostname for file serving node}
General troubleshooting steps
1. Run the exds_stdiag storage diagnostic utility.
2. Evaluate the results.
3. To report a problem to HP Support, see Escalating issues.
Escalating issues
The X9720 Network Storage System escalate tool produces a report on the state of the system. When
you report a problem to HP technical support, you will always be asked for an escalate report, so it
saves time if you include the report up front.
Run the exds_escalate command as shown in the following example:
[root@glory1 ~]# exds_escalate
The escalate tool needs the root password to perform some actions. Be prepared to enter the root
password when prompted.
There are a few useful options; however, you can usually run without options. The -h option displays
the available options.
It is normal for the escalate command to take a long time (over 20 minutes).
