6.0 HP X9000 File Serving Software File System User Guide (TA768-96043, October 2011)

• Update the Windows registry.
When using WebDAV shares in Windows Explorer, you must edit the Windows registry if
there are many files in the WebDAV shares or the files are large. Launch the windows registry
editor using the regedit command. Go to:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\WebClient\Parameters
Change the value of FileSizeLimitInBytes from the default value of 50000000 to
2147483648 (which is the value of 2 GB in bytes). Change the value of
FileAttributesLimitInBytes from the default value of 1000000 to 10000000.
• Enable debug logging on the server.
Edit the /usr/local/ibrix/httpd/conf/httpd.conf file and change the line
LogLevel warn to LogLevel debug. Next, restart Apache on the file serving nodes:
Use the following command to stop Apache:
/usr/local/ibrix/httpd/bin/apachectl stop
Use the following command to start Apache:
/usr/local/ibrix/httpd/bin/apachectl start
• Save documents during node failovers.
During a failover, MS Office 2010 restores the connection when the connection is lost on the
server, but you must wait until you are asked to refresh the document being edited. In MS
Office 2003 and 2007, you must save the document locally. After the failover is successful,
you must re-map the drive and save the document on the WebDAV share.
• When creating certificates, verify that the hostname matches the Vhost name.
When creating a certificate, the hostname should match the Vhost name or the domain name
issued when mapping a network drive or opening the file directly using the URL such as https://
storage.hp.com/share/foo.docx.
• Consider the assigned IP address when mapping a network drive on Windows.
When mapping a network drive in Windows, if the IP address assigned to the Vhost is similar
to the format 10.2.4.200, there should be a corresponding entry in the Windows hosts file.
Instead of using the IP address in the mapping, use the name specified in the hosts file. For
example, 10.2.4.200 can be mapped as srv1vhost1, and you can issue the URL https://
srv1vhost1/share when mapping the network drive.
• Unlock locked files.
Use the command BitKinex to unlock locked files if the files do not unlock before closing
the application.
• Remove zero byte files created by Microsoft Excel.
Microsoft Excel creates 0 byte files on the WebDAV shares. For example, after editing the
file foo.xlsx and saving it more than once, a file such as ~$foo.xlsx is created with 0
bytes in size. Delete this file using a tool such as BitKinex, or remove the file on the file system.
For example, if the file system is mounted at /ifs1 and the share directory is /ifs1/dir1,
remove the file /ifs1/dir1/~$foo.xlsx.
• Use the correct URL path when mapping WebDAV shares on Windows 2003.
When mapping WebDAV shares on Windows 2003, the URL should not end with a trailing
slash (/). For example, http://storage.hp.com/share can be mapped, but http://
