HP StorageWorks EVA Hardware Providers administration guide Windows 2003 (T1634-96054, August 2006)

4. Make sure you configured the VDS/VSS Configuration Utility as explained in Chapter 3
Installation.
5. Check configuration as explained in “Chapter 2 Configuration”:
• Check LAN connectivit y between all ser vers and the array.
• Make sure the firewall is open between all servers and the array.
• Check Command View server NIC bindings: the LAN that connects to the VDS/VSS server
must be listed first.
• Make sure you logged into all devices and software using administrator privileges.
• Visit the Microsoft website support knowledg e base and search for “VDS logging.” Turn on logging
as instructed by Microsoft and use the Microsoft procedure for testing VDS and checking the log.
VSS volume c
opying not working
1. Is the VSS HW P running? At the command prompt, type:
vssadm lis
tproviders
You should see the hpEVA VSS hardware provider listed.
2. Verify that the Business Copy license is installed. A BC license is required in order to produce
data copie
susingVSS.
3. Make sure
you configured the VDS/VSS Utility as explained in Chapter 3 Installation.
4. Check con
figuration as explained in Chapter 2 Configuration:
• Check CV workstation and VDS/VSS server connectivit y.
• VDS/VSS server not connected to the SAN corre ctly.
•Afirewal
l may be interfering with connectivit y between servers.
5. Review the Windows application event log, Windows system event log, and VSS trace to locate
errors in the snapshot process. See the Microsoft website and Windows help for information about
the log and trace files.
6. Use a process of elimination to determine which components are n ot working. You can do this
by tes
ting c omponents individually:
• TestVSSandthearraybyusingtheMicrosoftvshadow utility available i n the Microsoft VSS
Software Developer’s Kit to create snapshots. At the command line, type:
vshadow [drive letter]
The dr
ive letter is the production LUN you want to c opy. See the Microsoft documentation
for details about using vshadow.
• Test your backup application a nd VSS together by making a backup copy on a local drive,
bypa
ssing HWP and the disk array.
VSS copies intermittently fail or time out
VSS allows only 30 seconds for the entire snapshot process, including only 1 0 seconds for actually
making the copy. This narrow time window can cause any limitation in your system to hamper successful
snapshots. The following issues m ay affect system performance:
• Firewall or LAN traffic slowing or preventing commu n ication. Reconfigure the firewall or LAN to
increase throughput.
• Viruses slowing server o p eration. Check for and clean off viruses.
• VDS/VSS server is too slow. Use a fast, late mode CPU with sufficient memory.
• Inadequate privileges. Administrator privileges are required in all applications and on all
hardware used with HP VSS HWP.
• Writer application not configured according to best p ractices. Consult the software manufacturer
for recommended practices. For example, keeping database files small by creating more rather
