X9000 software manpages

X9000 software provides manpages for most X9000 software commands. To view the manpages,
set the MANPATH variable on the management console to include the path to the manpages and
then export it. The manpages are in the $IBRIXHOME/man directory. For example, if $IBRIXHOME
is /usr/local/ibrix, the default, you would set the MANPATH variable as follows and then
export the variable.
MANPATH=$MANPATH:/usr/local/ibrix/man

Configuring data collection with Ibrix Collect

Ibrix Collect is a log collection utility that gathers relevant information for diagnosis by HP Support.
For information about configuring Ibrix Collect, see "Collecting information for HP Support with
Ibrix Collect" in the administrator guide for your system.

Configuring HP Insight Remote Support

See the administrator guide for your system for information about configuring HP Insight Remote
Support on X9000 systems.

Creating file systems

For more information, see "Creating and mounting file systems" in the HP IBRIX X9000 Network
Storage System File System User Guide.

Configuring NFS exports (optional)

The GUI provides the easiest way to configure NFS exports. For more information, see "Using
NFS" in the HP IBRIX X9000 Network Storage System File System User Guide.
NOTE: On the Export Filesystem via NFS dialog box, change the path as needed to meet customer
requirements. The default value for path is the root directory of the file system. The other default
values on the dialog box should be adequate for most sites.

NFS client implementation tuning

NFS clients perform best when the file system policy on the X9000 file servers is tuned to prefer
LOCAL segments and ROUNDROBIN. This tuning ensures that NFS client writes will not suffer a
network hop penalty on writes to remote file serving nodes. To implement the tuning, place the
following script on the management console in /root, make the script executable and then run
it. The script runs commands necessary to tune servers for NFS performance.
#!/bin/bash
# LOCAL + ROUNDROBIN for NFS to write to local segments
# Do this for each segment server in your IBRIX Cluster
ibrix_fs -l |tail -n +3 |awk '{ print $1 }' > /tmp/.fs
ibrix_server -l |tail -n +3 |awk '{ print $1 }' > /tmp/.hosts
for fs in `(tac /tmp/.fs)`
do
for host in `(tac /tmp/.hosts)`
do
echo "ibrix_fs_tune on ${host}${i} LOCAL and ROUNDROBIN"
/usr/local/ibrix/bin/ibrix_fs_tune -f ${fs} -h ${host} -S LOCAL
/usr/local/ibrix/bin/ibrix_fs_tune -f ${fs} -h ${host} -p ROUNDROBIN
# This holds more files in cache (memory)
echo "Tuning cache on ${host}"
/usr/local/ibrix/bin/ibrix_host_tune -S -h ${host} -o "deleg_lru_high_wm=2000000,deleg_lru_low_wm=1999000"
# Set's the IBRIX threads to 64, this is similar to NFS threads
echo "setting IBRIX threads to 64"
/usr/local/ibrix/bin/ibrix_host_tune -t 64 -h ${host}
echo "Now set the NFS threads to 64 on your segment servers in /etc/sysconfig/nfs variable RPCNFSDCOUNT, I do
not do this automatically incase you already tuned your NFS"
