Hi Walter,
a second very similar bug is also there - https://tools.cisco.com/bugsearch/bug/CSCut61527
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
experienced your bug aswell some time ago :/ - there seem to be some stuff going on with the SAS controllers in the B200 M4 ... had some issues lately

hi all, can anybody explain me in detail how multicast traffic is forwarded between UCS blades? MAC adresses from on ServerPorts are learnd - those managed by the UCS wont age out. Unknown unicasts are dropped on uplink ports broadcast traffic is forwarded to all servers. regarding multicast traffic I only found the following statement: Server-to-server multicast and broadcast traffic is sent through all uplink ports in the same VLAN. but 2 Blades on UCS dont receive Multicast Traffic from eachothe - by default. any ideas regarding this issue? Thx lukas

hi all, i wanted to test the scenario that if one blade fails the service profile can simply be applied to another blade and with local disks you just have to replace the disks. And exactly here is my problem: when i replace the hdds (with ESX installed) in Raid 1 configuration and plug them into another blade, apply the service profile(of the "failed" blade) to the new blade and boot it the system is not able to boot because it does not see the LUN/Volume. have i forgotten a step?? thanks in advice for any hints. thx lukas
