Description (partial)
Symptom: B200 M4 rebooted unexpectedly A deep discovery is observed from the UCSM tech-support, rather than the intended shallow discovery Conditions: Any operation that triggers a shallow discovery could transition to a deep discovery if the Serial number of the blade's MRAID12G RAID controller is blank. Even after the unexpected reboot and deep discovery, UCSM "show server inventory expand" output will show a blank SN for the MRAID12G RAID controller: RAID Controller 1: Type: SAS Vendor: Cisco Systems Inc Model: UCSB-MRAID12G Serial: HW Revision: C0 PCI Addr: 01:00.0 Raid Support: RAID0, RAID1 OOB Interface Supported: Yes Rebuild Rate: 30 Controller Status: Optimal Example operations that will trigger a shallow discovery: CIMC Reset UCS Manager Upgrade UCS Manager Cluster lead operation IOM Reboot/Reset IOM Offline Event due to cable disconnect/reconnect Fabric Interconnect Reboot Note: The UCSB-MRAID12G RAID controller is an optional/removable component on the B200-M4. If no attributes are populated in the show server inventory expand command output for Raid Controller 1, then it is not installed and you are not impacted. Example: RAID Controller 1: Type: SAS Vendor: Model: Serial: HW Revision: PCI Addr: Raid Support: OOB Interface Supported: No
