The site was locked and I was tried to unlock the site using
stsadm and powershell commands in sharepoint 2013 but didn’t worked.
Finally I found below PowerShell from the MS forum to unlock
the site and it got worked.
$Admin = new-object
Microsoft.SharePoint.Administration.SPSiteAdministration('http://root.toto.com')
$Admin.ClearMaintenanceMode()
$site.MaintenanceMode
NOTE: The above commands will work
only if your SharePoint 2013 April cumulative update installed
