HP 3PAR X9000 File Serving Software (IBRIX) Implementation Guide (QL226-96987, June 2013)

For example, to perform failback of the failover server “eos172s1.vpi.hp.com”, issue the
following command:
# ibrix_server –f –U –h eos172s 1.vpi.hp.com
After the failback completes, the state of the file system is restored to “Mounted”. The state of the
server also is restored to “Up”.
For more information about these commands, see the HP StoreAll Storage CLI Reference Guide,
which is available on the following HP website:

Using Case Insensitivity
By default, HP StoreAll Storage file systems and directories follow Portable Operating System
Interface (POSIX) semantics, and file names are case-sensitive for Linux/NFS users—that is, abc
and ABC are two different files. If you prefer to use Windows semantics for Linux/NFS users, you
can make a file system or subdirectory case-insensitive, such that abc and ABC are the same file
name. Thus, once abc is created, you would not be allowed to create a file named ABC.
NOTE: Before enabling the case-insensitive feature:
• The file system or directory must be created under the HP StoreAll OS software 6.0 or later
release.
• The file system must be mounted. See “Mounting a File System” (page 28).
The case-insensitivity feature can be enabled or disabled using either the StoreAll OS CLI or GUI.
This section describes general steps and commands that are required to use the case-insensitivity
feature with the StoreAll OS CLI.
1. Create a mounted file system on the StoreAll 9300 hosts using the LUNs that are exported to
the StoreAll 9300 from HP 3PAR. See “Mounting a File System” (page 28).
2. After creating a mounted file system, you need to check the status of the case-insensitivity
setting before changing it. To check the status of the case-insensitivity setting, use the following
command:
# ibrix_caseinsensitive -i -f FSNAME -p PATH [-r]
For example, to check the status of the case-insensitivity setting of file system fs1 mounted at
the path /fs1, issue the following command:
# ibrix_caseinsentive –i –f fs1 –p /fs1
3. Depending on the result of the preceding command, you can now change the case-insensitivity
setting by using the following command:
# ibrix_caseinsensitive -s -f FSNAME -c [ON|OFF] -p PATH
For example, to change the case-insensitivity setting to OFF (that is, making it case-sensitive)
for file system fs1 located at /fs1, issue the following command:
# ibrix_caseinsensitive –s fs1 –c OFF –p /fs1
