HCM does not restrict duplicate WWNs if BCU is used to create V_Ports
Problem
The HCM GUI should post an error message for duplicate V_Ports (detected in the Vports.db file)
and prompt the user to remove the duplicate when it detects duplicate world wide names (WWNs),
but it does not. The HCM does not restrict duplicate WWNs when the BCU is used to create V_Ports.
Workaround
Do not use the BCU for virtual port management, because it does not handle duplicate V_Port
world wide names. Instead, use only the HCM GUI to manage V_Ports.
RHEL4 U7 x86/x64 OS crashes after invalid operand from hcmagent
Problem
With HCM open, the RHEL4 U7 x86/x64 operating system hangs within five to ten minutes of
sitting idle. This happens only on RHEL4 U7 x86 kernel version (2.6.9-78). The error message in
the /var/log/messages file indicates an illegal operand in the HCM agent.
Workaround
Upgrade the kernel to the latest patch release: from 2.6.9-78 to 2.6.9-78.0.5.
