6.2 HP IBRIX 9300/9320 Storage Administrator Guide (AW549-96049, December 2012)

8. 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 6.2 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 HP IBRIX 9000 Storage File System User Guide for more information about
this feature. Whenignore_writethru is enabled, IBRIX software ignores writethru buffering
to improve SMB write performance on some user applications that request it.
9. Mount file systems on Linux 9000 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 IBRIX 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 153).
• Data retention. Files used for data retention (including WORM and auto-commit) must be
created on IBRIX 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 “Upgrading pre-6.0 file systems for software snapshots” (page 153).
11. Review the file /etc/hosts on every IBRIX node (file serving nodes and management nodes)
to ensure the hosts file contains two lines similar to the following:
127.0.0.1 <hostname> localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
In this instance, <hostname> is the name of the IBRIX node as returned by the hostname
command.
If these two lines do not exist or they do not contain all of the information, open the /etc/
hosts file with a text editor such as “vi” and modify the file so it contains the two lines,
matching the format provided in this step. For example, if the hostname command returns
ss01, then the lines should appear as follows:
127.0.0.1 ss01 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
12. After the upgrade, the Fusion Manager on each server in the IBRIX cluster must be restarted
manually.
