After LUN Resignature, Unable to see that a LUN is Connected to a Host
Details
In a VMware ESX host, if you have a datastore volume on a SCSI LUN, and you change the LUN ID assignments on the iSCSI target side so that it uses a different LUN number, vCenter no longer recognizes this LUN due to mismatch of UUID and LUN ID.
In the vCenter Configuration/Storage Adapters page, do the following:
Rescan the data adapters to find the altered LUN.
In Storage, select Add Storage.
Select the LUN that matches the altered LUN parameters.
Select to resignature the LUN.
The LUN is resignatured and added to Datastore list in Lab Manager.
Solution
After the resignatured datastore appears in Lab Manager in the list of datastores, you must associate it with the information that Lab Manager had for the datastore before it was resignatured.
To associate a resignatured datastore with the information that Lab Manager had before the resignaturing:
1. Login to the Lab Manager Web console as an system administrator.
In Old datastore, select the name of the datastore before it was resignatured.
In Resignatured datastore, select the new datastore entry that appeared in Lab Manager after resignaturing.
Click OK.
The Associate Server checks whether the Lab Manager list of files and the actual files on the datastore match and begins to combine the two datastore entries, You can view the progress of the task in the Activity Log page. When the process is complete, you need to log in to vCenter and refresh the datastores to insure that everything is up to date.
