Resolving a Password Mismatch
When the vCenter Plug-in password and the storage array password do not match, you can run passive, read-
only commands, such as Read and View, on the storage array; however, active, read/write commands to the
array, such as create and delete, will fail. The vCenter Plug-in displays the properties of the storage array
whether the passwords match or do not match. To resolve a password mismatch, perform the previous
procedure, Changing a Storage Array Password.
Storage Array Configuration Backup
Version 2.2 of the vCenter Plug-in supports storage array configuration backups to script files that may be
applied to a storage array from the Dell Modular Disk Storage Manager (MDSM). These script files will
facilitate the restoration of the storage array configuration, such as storage array name, disk group
configurations, virtual disk names, virtual disk capacities, etc. IT WILL NOT BACKUP DATA RESIDING
ON THE STORAGE ARRAY! A traditional backup strategy must still be employed to provide recovery of
user data residing on the virtual disks.
CAUTION: Only the storage array configuration information is saved during the
save configuration operation, NOT data stored on the virtual disks.
NOTE: Only the base storage array configuration information is saved. Objects such as snapshots,
virtual disk copies, and remote replications are not saved to the script file.
The vCenter Plug-in Automatic Save Configuration will perform a save configuration of the storage array after
a configuration event has occurred on the storage array, either from the vCenter Plug-in or from MDSM. A
storage array modification event will start a 4 minute timer, on the application server, at the time of the event
on the storage array. If within that 4 minute time window, no other configuration events have occurred on the
storage array, a save configuration will occur. If another modification event occurs within the 4 minute time
window, the timer will be reset to 4 minutes. When no modification events are detected on the storage array
within the 4 minute window, a save configuration will be performed. Automatic Save Configuration will
maintain the last 15 save configuration script files.
Enable Automatic Save Configuration Backups
These backups can be set to automatic or manually initiated. To enable automatic backups of the storage array
base configuration, perform the procedure below:
1
Open the Storage Array Manager View. See Figure 14.
2
In the left pane, click the name of the storage array.
The storage array properties are displayed in the right pane.
3
In the right pane, click Automatically Save Configuration link.
The Automatically Save Configuration dialog box appears. See Figure 16.
