Hello,   No, you don't need the legacy versions at all.  That would only be needed if you were using much older firmware.   The firmware update instructions on the version you want to end up at (10.0.3) has the exact steps.   So you are at 7.1.x, you go to 8.1.X where X is most current version.  Reboot. Then 8.1.x to 9.1.9 reboot, then 9.1.0 to 10.0.3.    Also check to see if there are any drives that need their firmware updated.    With the Firmware downloads is a document "OS considerations..."   That will show you how to set or verify your disk timeouts are set correctly.   That also applies to any VMs you might be running, and the hypervisor host.  For VMware there is a separate best practices guide as well.  TR1091   [URL] Also best to do firmware updates during a quiet IO time to reduce the failover time.   Regards,  Don 
I am planning to update the firmware on a Dell Equallogic PS 6100. It is currently running firmware version 7.1.5. I went onto eqlsupport.dell.com to get the .zip file to upload the firmware update. I see the have three versions listed as recommended ps series firmware: 10.0.3, 9.1.9, and 8.1.15. I also see there is a section called Legacy version. Do I need to go to the legacy versions and start with version 7.1.7 or can I do one of the recommended ones such as 10.0.3, 9.1.9, and 8.1.15?    I did verify there is no replication on the SANs and the available storage space is good. I just want to make sure I am well planned for updating the firmware.
