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 StoreAll systems.
Creating file systems
For more information, see “Creating and mounting file systems” in the HP StoreAll Storage 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 StoreAll Storage 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 StoreAll 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 StoreAll 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 StoreAll threads to 64, this is similar to NFS threads
echo "setting StoreAll 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"
done
done
Configuring SMB shares (optional)
NOTE: Before attempting to configure SMB, ensure that the DNS entries for the user network IP
addresses have PTR (reverse lookup) records configured.
