Issue Detecting MX5016s Disks with PERC H755MX on MX7000 Chassis and MX750c Blades

Hello everyone,

I'm experiencing an issue with detecting disks from the MX5016s storage module on a Dell EMC MX7000 chassis configured with:

• An MX5000s I/O module.
• Two MX750c blade servers with PERC H755MX controllers.

Problem Description:

1. Internal disks on the blades are detected correctly using the command:

   racadm storage get pdisks

   However, the disks from the MX5016s are not visible.

2. The command to list enclosures only shows the internal enclosure:

   racadm storage get enclosures
   Enclosure.Internal.0-0:RAID.Integrated.1-1

   No mention of the MX5016s.

3. I attempted to force a rescan with:

   racadm storage rescan

   Error received: Invalid command specified.

4. The SAS ports are active, and the MX5000s module is in Passive mode.

5. The PERC H755MX is in RAID mode, and I want to avoid losing the existing RAID configurations.

6. The logs only show events related to internal disks with no errors concerning SAS or the MX5016s.
