HP StorageWorks SAN Virtualization Services Platform 2.1 release notes (5697-8060, March 2009)

cannot be opened.) Some of the files may be locked by another user or application (like Remote

Desktop), or you need to delete these sessions before running Java Web Services.

Suspend active snapclone or migration tasks before deleting

If you have a virtual disk doing snapclone or migration tasks, and delete that task in the middle of

the data moving process (without suspending it first), the task becomes stuck and never completes the

deletion. When this issue occurs, you should perform the VSM failover procedure (through Tools >

Maintenance, and perform Failover VSM) in order to be able to complete the deletion process.

IPv6 support limitations

The following are limitations with IPv6 support:

• Communications between VSM servers and the web server (running on the VSM server) and the

CORBA layer is still based on IPv4 addresses. In addition, the SaSnap utility needs an IPv4 address

to fetch the data from a remote VSM server. Consequently, each VSM server must have at least

one IPv4 address, but may have IPv6 addresses as well.

NOTE:

All the above communications are confined to the SVSP domains. External communications (for

example, the GUI and other SOAP clients connected to the web server) are done according to the

site configuration (either through IPv4 or IPv6 addresses).

• If an IPv6 address is added or deleted while VSM is running, the VSM Monitor cannot detect this

change without restarting the VSM application.

• Downloading the VSM GUI client for IPv6 (for example, when IPv6 is configured as the desired

communication protocol between the web server and the client) must be done using the Microsoft

Internet Explorer 7 or Mozilla Firefox (version 3.0.3 and higher) browser. There is a known limit-

ation with Microsoft Internet Explorer 6, and it cannot be used.

• To log into the VSM GUI using IPv6 format, you need to enclose the address within right and left

brackets. For example: [fd00::21d:9ff:fe6b:1da9].

PiT deletions after reaching threshold Guard level

There are three configurable capacity threshold limits: Warning, Guard, and Emergency. When the

Guard level is reached, more than one of the older PiTs may be deleted. See the HP StorageWorks

SAN Virtualization Services Platform Manager user guide for details.

Incorrect number of paths displayed for clustered virtual disks

After adding presentations to a clustered virtual disk to more than one host, occasionally some of the

hosts do not display the correct number of paths. In these cases, perform the following:

1. Set the presentation to one UDH only.

2. Rescan for new devices.

3. Count the number of paths.

4. Set presentations to the second UDH.

5. Rescan for new devices.

6. Count the number of paths.
