OpenVMS Host I/O Must be Stopped Before Upgrading from pre-V6.2.0.x to V6.2.0.x or Higher

Flash (Alert)


OpenVMS hosts on Storwize V7000 or SAN Volume Controller clusters running V6.2.0.x or higher will experience a loss of access to Volumes, until the hosts' -type attribute has been changed to "openvms".


The V6.2.0.3 PTF and V6.3.0.0 GA release and higher re-instate support for OpenVMS hosts,by introducing a new host type, "openvms".

Customers running pre-V6.2.0.x code with OpenVMS hosts must stop all I/O from these hosts before the upgrade process is started. Once the upgrade process has completed, all OpenVMS host objects must have their -type attribute changed to "openvms", before host I/O can be restarted. This can be achieved using the following CLI command:

svctask chhost -type openvms <host name/ID>

Any OpenVMS hosts attempting to perform I/O to a Storwize V7000 or SAN Volume Controller cluster running V6.2.0.x or higher without the correct -type attribute set, will experience loss of access to any Volumes mapped to those hosts.
