Resolving a problem with Microsoft Windows disk manager
Microsoft Windows disk manager might hang if the host attempts to write to a LUN that is a remote copy secondary volume on a Storwize® V3700 system. This procedure addresses this issue.
If the disk manager hangs and you think it might be because of a write to a remote copy secondary volume, then you can configure Storwize V3700 to hide remote copy secondary volumes from that host.
You can specify the host type of hide_secondary to make all remote copy relationship secondary volumes unavailable to that host.
Use the Storwize V3700 management
GUI to set the host type to hide_secondary, or
use the Storwize V3700 command
line interface to run either of the following commands.
chhost -type hide_secondary hostname/id
or
mkhost -name my_host -fcwwpn WWPN1:WWPN2 -type hide_secondary
