HP StorageWorks Scalable File Share - Manual (Page 161)

Verifying the system 6–31
CAUTION: Using NFS on an Object Storage Server is not generally supported, as it may
seriously interfere with Lustre operation. Do not use NFS while Lustre is operating, and do not use
NFS as a general file exchange mechanism between servers.
To run the
qselantest
diagnostics on an Object Storage Server, perform the following steps:
1. Log in to the Object Storage Server that is to be tested, and connect to the server where the
administration service is running by entering the following command:
# ssh hplsadm
2. Export the administration server drive by adding a line similar to the following to the
/etc/exports
file:
/ 192.168.0.0/16(no_root_squash)
This line specifies the address/mask of the management network subnet—in this example, the
192.168 subnet; if your management network subnet is different, change the line as necessary.
3. Start the NFS server by entering the following command:
# service nfs restart
4. Enter the
exit
command to return to the Object Storage Server.
5. Connect to the administration server drive, as follows:
# mkdir /mnt/adm
# mount -t nfs -o nolock hplsadm:/ /mnt/adm
6. Set the PATH and LD_LIBRARY_PATH environment variables, as follows:
# PATH=$PATH:/mnt/adm/usr/bin
# export PATH
# LD_LIBRARY_PATH=/mnt/adm/usr/lib/qsnet/elan4/lib
# export LD_LIBRARY_PATH
7. Run the diagnostics by entering the following commands:
# cd /mnt/adm/usr/bin
# ./qselantest
See Section 6.1.8.3.3 for an example of output from a
qselantest
test that detected no errors.
8. When the test is finished, disconnect from the administration server drive by entering the following
commands:
# cd /
# umount /mnt/adm
9. Stop the NFS server on the administration server by entering the following command (on the Object
Storage Server):
# ssh hplsadm service nfs stop
10. Enter the
exit
command to quit the Object Storage Server. This automatically sets the
PATH
and
LD_LIBRARY_PATH
environment variables to their original values.
Note that you must quit the Object Storage Server in order to set the
PATH
and
LD_LIBRARY_PATH
environment variables to their original values. If necessary, you can then connect to the Object
Storage Server again.
