Cause

Such behavior was classified as the software issue PBAS-30310 and was fixed in OBAS 4.5.7 release.

Resolution

To resolve the issue, please upgrade to 4.5.7 as described in How to upgrade OBAS system to the latest available version.

Workaround for 4.5.6

If upgrade is not an option for you, there is a hotfix for 4.5.6 version. To install it, please download 64-bit hotfix or 32-bit hotfix depending on your OS and install it by running the commands below.

For 64-bit OS:

# rpm -Uvh hspc-dm-ns-plugin-ssh-4.5.6-35.swsoft.x86_64.rpm

For 32-bit OS:

# rpm -Uvh hspc-dm-ns-plugin-ssh-4.5.6-35.swsoft.i386.rpm
