13 Troubleshooting VCEM

IMPORTANT:

VCEM 6.3 supports the Microsoft Internet Explorer 8 (IE8) browser, but the

underlying Virtual Connect Manager does not currently provide the same level of support. Using
IE8 to perform VCEM Domain Maintenance tasks that access Virtual Connect Manager might result
in failed or incomplete operations. HP recommends Microsoft Internet Explorer 7 (IE7) or Firefox
3.0 or 3.5 as the preferred browsers for use with VCEM. For a list of browsers supported by Virtual
Connect Manager, see the HP Virtual Connect for c-Class BladeSystem User Guide.

When you are upgrading to a new and different CMS, or are moving to a 64-bit CMS, you might
need to migrate your data by using the Systems Insight Manager data migration tool. If you are
upgrading to a new version of VCEM on the same CMS, data migration with the Systems Insight
Manager data migration tool is not necessary. For more information, see the Data migration of
an existing MS Windows CMS to a new Insight Software 6.0 system
white paper on the Systems
Insight Manager Information Library at

Communicating with the enclosure OA

Although VCEM may report the VC Domain status as Managed by VCEM (green status) on the VC
Domains tab, the VC Domain might be indicating a different overall status which is not displayed
in the VCEM GUI. If the VC Domain has lost communication with the enclosure OA, Virtual Connect
Manager (VCM) reports this problem by modifying the VC Domain status. However, the VCEM
GUI does not directly report it and the only indicator for the communication issue will be one of
the following error messages displayed when VCEM is trying to communicate with VCM.

Error message A

The operation cannot be performed because the VC Manager has lost communication with the enclosure's
[enclosure name] Onboard Administrator (OA). This communication issue could be intermittent. Go to VC
Manager to check the status of all the enclosures associated with that VC Domain. See the Virtual Connect
user guide for more information if there is a lost communication.

Error message B

The operation cannot be performed because the VC Manager has lost communication with the enclosure Onboard
Administrator (OA). This communication issue could be intermittent. Go to the VC Manager to check the
status of all the enclosures associated to that VC Domain. If there is a lost communication, go to Virtual
Connect user guide to get information on how to resolve this issue.

Once VCEM returns one of the error messages above, you must go to the VCM GUI and check
the VC Domain overall status to see if it is still reporting the communication problem with the
enclosure OA and then see the HP Virtual Connect Manager User Guide to resolve the situation.

MAC, WWN, and Serial Number management

You must verify that VC Domains within a network have unique MAC addresses, WWN addresses,
and serial numbers. Adding a VC Domain to a VC Domain Group or creating a VC Domain Group
does not verify that the profiles in a VC Domain use MAC or WWN addresses allocated in the
VCEM external address pool. You can overwrite the external addresses to become in use status.
To prevent external addresses from use in VCEM, add the addresses to the exclusion addresses
pool. If you plan to add the VC Domain back to VCEM, then you must also remove these addresses
from the exclusion addresses pool.

Adding or removing VC modules to VC Domain Group Configuration

To add or remove VC modules to all VC Domains managed by a VC Domain Group:
1.

Go to VCEM, click the VC Domain Groups tab, select the desired VC Domain Group where
you want to add or remove VC modules, and then click Delete. For more information, see the

“Deleting a VC Domain Group” (page 58)
