Troubleshoot SCVMM Issues

SCVMM relies on storage providers such as SMP when performing storage provisioning tasks. When using SMP, loss of connectivity to

the managed PS groups might adversely affect these operations. Note that connectivity has to be ensured on the SCVMM management

host as well as on all managed hosts or clusters involved in provisioning tasks using SMP.

The two most common causes for a loss of connectivity to PS Series groups are:

•

Incorrect or invalid credentials to the group. For example, user credentials have changed on the group and have not been updated on

the SCVMM management host. If you enabled SSO (single sign-on) when you configured the group, authentication failures might also

be caused by the status of the account in Active Directory (for example, expiration of account credentials and possibly other policies).

See your Active Directory documentation for further steps in troubleshooting these situations.

•

Actual loss of network connectivity to the group for a number of different reasons, including but not limited to the group being

temporarily offline (for example, for maintenance).

Troubleshooting PS Series group connectivity issues is outside the scope of this document. However, after connectivity is restored, use

the following steps to verify correct configuration of storage resources on the SCVMM management host:

1.

Refresh or rescan the SMP in

VMM

.

Rescanning can be more time consuming than refreshing because it invalidates the provider cache across all of the configured storage

groups. Rescanning retrieves objects from the PS Series groups and updates the local cache in the provider. Refreshing updates the

state of SCVMM by reading the objects from the provider cache without invalidating the cache.

2.

After starting a refresh or rescan operation, view the status of the job in the

Jobs

workspace.

3.

When the job completes, return to the

Providers

view in the

Fabric

workspace (click

Fabric

→

Providers

) to confirm that the status

of the SMP is responding.

4.

If the SMP status is not responding, make sure the PS Series group is accessible to the SCVMM Host, either:

•

Use the PowerShell Tools cmdlet

Get-EqlGroupAccess

to verify the group is configured. If the group does not appear, then

use the

New-EqlGroupAccess

cmdlet to configure the group. See the

Dell EqualLogic PowerShell Tools Reference Guide

for

more information.

•

Use the ASM GUI and configure access to the group in the PS Group Access settings screen. Click

Add PS Group

to add your

group. See the

Dell EqualLogic Auto-Snapshot Manager/Microsoft Edition User’s Guide

for more information. To test availability

of storage resources from a particular group run the PowerShell Tools cmdlet

Get-StorageSubSystem

and make sure the

group is listed in the output. After confirming that the group is accessible, repeat step 2.

5.

Make sure that storage resources on the library shares are accessible.

a)

Open an iSCSI session from

Server Manager of VMM

.

b)

Make sure the iSCSI targets for the template volumes are shown as connected; if not, reconnect them.

c)

Open

Disk Management

. Click

Administrative Tools

→

Computer Management

→

Disk Management

and make sure the

disk corresponding to the active iSCSI target is currently online. Set the disk online if needed.

d)

Make sure that the volumes still have the correct access paths (mount points) under the library shared folder.

e)

Refresh the library shares in the

VMM Library

workspace view. Click

Library

→

Library Servers

.

6.

In the

Library

workspace view, right-click

VM Templates

, then select

Refresh

from the menu.

7.

Confirm that both the VHD and VM template resources are enabled for SAN operations in the

SAN Copy Capable

property field. If

correctly configured, this property says Yes. This setting ensures that rapid provisioning is enabled for these resources.

To troubleshoot connectivity on the managed hosts, make sure that PS Series group access is correctly configured (for example, by

running the PowerShell Tools cmdlet

Get-EqlGroupAccess

) and make sure the iSCSI targets for volumes deployed to these hosts

are correctly connected.
