Pre-upgrade Steps

On Appliance

Perform the following steps on your appliance prior to disk firmware upgrade.

  • Backup the data on your appliance using a Cloud Snapshot or a Cloud Clone. The time taken by this step depends upon the amount of data residing on your appliance and could vary from a few hours to days.
  • Take a Configuration Backup by navigating to Home → Manage → Configuration Backup and clicking the 'Download' button.
  • Check for any other active backup jobs that are running on the system. This includes the jobs on the Web UI and those on DPC host. Wait for the current jobs to complete. 

On Host

Perform the following steps on the host prior to disk firmware upgrade.

  • Stop all the host I/Os on StorSimple volumes.
  • Choose the next set of steps based on whether you are on a Windows, VMware or Linux host.
On Windows Host

Perform the following procedure on Windows host:

  • If it is possible to do so, please shut down your Windows host.
  • If it is not possible to shut down your Windows host, please follow the pre-upgrade steps listed in Appendix I - Advanced Procedure for Windows Host to take the volumes offline and disconnect the iSCSI session.
On VMware vSphere Host

On VMware, the upgrade can be performed without taking the volumes offline. Depending upon whether the ESX server is hosting only StorSimple volumes or StorSimple and non-StorSimple volumes or mixed disks, the steps required are different.

ESX/ESXi server has VMs with only StorSimple Volumes

In this scenario, the ESX server has VMs that have all the VMDKs only on StorSimple volumes.

  • Power off all the VMs.
  • Place the ESX server in ‘Maintenance Mode’.
    • Connect to ESX server using vSphere client.
    • Right-click the ESX server and select ‘Enter Maintenance Mode’.

ESX/ESXi Server has VMs with StorSimple volumes and VMs with Non-StorSimple Volumes

In this scenario, the ESX server has some VMs that are running on StorSimple volumes and other VMs running on non-StorSimple volumes.

  • Power off VMs that are hosted on StorSimple volumes only.

ESX/ESXi Server has VMs with mixed disks

In this scenario, the VM has a VMDK on a StorSimple volume and another VMDK on a non-StorSimple volume.

  • Power off the VMs.
On Linux Host

Perform the following procedure on Linux host:

  • If it is possible to do so, please shut down your Linux host.
  • If it is not possible to shut down your Linux host, please follow the pre-upgrade steps listed in Appendix II - Advanced Procedure for Linux Host to unmount the volumes and disconnect the iSCSI session.
