6.
If you are using SMB, set the following parameters to synchronize the SMB software and the
Fusion Manager database:
smb signing enabled
smb signing required
ignore_writethru
Use ibrix_cifsconfig to set the parameters, specifying the value appropriate for your
cluster (1=enabled, 0=disabled). The following examples set the parameters to the default
values for the 6.1 release:
ibrix_cifsconfig -t -S "smb_signing_enabled=0,
smb_signing_required=0"
ibrix_cifsconfig -t -S "ignore_writethru=1"
The SMB signing feature specifies whether clients must support SMB signing to access SMB
shares. See the
this feature. Whenignore_writethru is enabled, IBRIX software ignores writethru buffering
to improve SMB write performance on some user applications that request it.

Mount file systems on Linux 9000 clients.

Because of a change in the inode format, files used for snapshots must either be created on
IBRIX 6.0 or later, or the pre-6.0 file system containing the files must be upgraded for snapshots.

Upgrading Linux 9000 clients
Be sure to upgrade the cluster nodes before upgrading Linux 9000 clients. Complete the following
steps on each client:
1.
Download the latest HP 9000 client 6.1 package.
2.
Expand the tar file.
3.
Run the upgrade script:
./ibrixupgrade -f
The upgrade software automatically stops the necessary services and restarts them when the
upgrade is complete.
4.
Execute the following command to verify the client is running IBRIX software:
/etc/init.d/ibrix_client status
IBRIX Filesystem Drivers loaded
IBRIX IAD Server (pid 3208) running...
The IAD service should be running, as shown in the previous sample output. If it is not, contact HP
Support.
Installing a minor kernel update on Linux clients
The 9000 client software is upgraded automatically when you install a compatible Linux minor
kernel update.
If you are planning to install a minor kernel update, first run the following command to verify that
the update is compatible with the 9000 client software:
/usr/local/ibrix/bin/verify_client_update <kernel_update_version>
The following example is for a RHEL 4.8 client with kernel version 2.6.9-89.ELsmp:
# /usr/local/ibrix/bin/verify_client_update 2.6.9-89.35.1.ELsmp
nl
Kernel update 2.6.9-89.35.1.ELsmp is compatible.
If the minor kernel update is compatible, install the update with the vendor RPM and reboot the
system. The 9000 client software is then automatically updated with the new kernel, and 9000
client services start automatically. Use the ibrix_version -l -C command to verify the kernel
version on the client.
