Upgrading Linux Storeall Clients; Installing A Minor Kernel Update On Linux Clients - HP StoreAll 9730 Administrator's Manual

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 6.3 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
feature. When ignore_writethru is enabled, StoreAll software ignores writethru buffering
to improve SMB write performance on some user applications that request it.
9. Mount file systems on Linux StoreAll clients.
10. If you have a file system version prior to version 6, you might have to make changes for
snapshots and data retention, as mentioned in the following list:
Snapshots. Files used for snapshots must either be created on StoreAll software 6.0 or
later, or the pre-6.0 file system containing the files must be upgraded for snapshots. To
upgrade a file system, use the upgrade60.sh utility. For more information, see
"Upgrading pre-6.0 file systems for software snapshots" (page
Data retention. Files used for data retention (including WORM and auto-commit) must be
created on StoreAll software 6.1.1 or later, or the pre-6.1.1 file system containing the
files must be upgraded for retention features. To upgrade a file system, use the
ibrix_reten_adm -u -f FSNAME command. Additional steps are required before
and after you run the ibrix_reten_adm -u -f FSNAME command. For more
information, see
1 1. If you have an Express Query enabled file system prior to version 6.3, manually complete
each file system upgrade as described in
Express Query enabled file systems" (page

Upgrading Linux StoreAll clients

Be sure to upgrade the cluster nodes before upgrading Linux StoreAll clients. Complete the following
steps on each client:
1. Download the latest HP StoreAll client 6.3 package.
2. Expand the tar file.
3. Run the upgrade script:
./ibrixupgrade -tc -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 StoreAll 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 StoreAll 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 StoreAll client software:
/usr/local/ibrix/bin/verify_client_update <kernel_update_version>
