Windows PowerShell Dell EqualLogic PS Series Volume Deletion and iSCSI Connection removal Automation Start Take OS volume offline Disconnect iSCSI sessions to volume … 6. Next logout of each iSCSI Session connected to the volume. The iSCSI targets are still associated to the $colSessions variable assigned earlier with the WMI command (see step 3): PS C:\> foreach ($objSession in $colSessions) { write-host "Host $hostn - logging out ISCSI target $iTARGET" $retn = $objSession.
Windows PowerShell Dell EqualLogic PS Series Volume Deletion and iSCSI Connection removal Automation Start Take OS volume offline Disconnect iSCSI sessions to volume … 7. Remove the persistent connections – this time the persistent login class will be used “MSiSCSIInitiator_PersistentLoginClass” for the WMI command: PS C:\> $colPersistent = get-wmiobject -computername $hostn -namespace root\WMI -class MSiSCSIInitiator_PersistentLoginClass | where { $_.
Windows PowerShell Dell EqualLogic PS Series Volume Deletion and iSCSI Connection removal Automation Output will look similar to below: PS C:\ > foreach ($objPersistent in $colPersistent) { write-host "Host $hostn - removing persistent target:" $objPersistent.TargetName $objPersistent.psbase.Delete() } Host CFW2K12CC2 - removing persistent target: iqn.2001-05.com.equallogic:0-8a0906097bba009-7528bae58ce50f9a-td1089v1 PS C:\ > Start Remove Windows Volume Take EQL volume offline Delete EQL Volume End 9.

Now remove the volume PS C:\> Remove-EqlVolume -VolumeName $ThisVol -Force Note: “-Force” will bypass the confirmation message Output will look similar to below: PS C:\> Remove-EqlVolume -VolumeName $ThisVol -Force PSAPI.Cmdlets.RemoveVolume TD1089VOL1 completed successfully.
Windows Server 2012 Native Windows Storage Management Automation Techniques Windows Server 2012 Native Windows Storage Management Automation Techniques Windows Server 2012 and Windows 8 introduced a new Storage Management Architecture to help reduce management complexity as well as optimize storage through native Windows Storage Management Applications. Host Integration Tools for Microsoft v4.
Add volumes example with native Windows Server 2012 cmdlets The details we needed in Windows 2008 to just retrieve the Physical disk number to initialize, partition and format are much easier to obtain with the new Storage Architecture of Windows Server 2012 Also the new iSCSI Session cmdlets connect and bring the volume online consolidating some of the steps.

Conclusion Dell® EqualLogic Host Integration Tools for Microsoft® along with Auto-Snapshot Manager Microsoft® Edition (ASM/ME) provide robust integration and management capabilities for Dell PS Series storage. The exercises in this document should provide some guidelines on how Dell PS series storage environments may be best automated to improve management simplicity and optimization.
Appendix A: Full Script to add a volume (Windows 2008) This is the full script built from the step by step guide we introduced in the previous sections. This script may be run on Windows 2008 or Windows Server 2012/Windows 8. Note: This script will need access to the PS Series Array Group and the volume must not exist. Launch the Windows ISE and create a new PowerShell script (File -> New) and copy and paste the following.
