I have seen customers do this with the raid controllers that ship with the 3260's. HOWEVER, due to the very large storage capacity of the 3260's, I would not do this on large number of drives. I have had several customers that tried to expand /modify a 150TB virtual drive, and it literally took weeks to complete, and then they had issues with the resulting expanded VD. If this is just working with a few drives, and you can schedule a good block of time to let the expansion run offline (don't boot to OS) or application that would by trying to trigger I/O to the VD being modified/reconstructed, then you may be successful.   Kirk... ...

I'm not sure I fully understand your current topology. If you are not doing iSCSI boot from san, I would think you could simply modify your current vnic that carries iscsi traffic to allow/trunk your additional/new iSCSI vlan.  Then add an additional vmk iSCSI port bound with new vlan to the same vmnic. Ideally, you would create an additional vnic, with just the new iSCSI vlan, and have the additional VMK iSCSI port bound to it's corresponding vmnic.   Kirk... ... View more

Theoretically, if you have a megaraid controller such as 9271, or newer 12Gb models, there is is something called raid migration. See https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/3rd-party/lsi/mrsas/userguide_june_2017/pub-005110_DB15-001199-08_2017-06-09_MR-614-SW-UG.pdf   I posted some examples on using the CIMC GUI to expand a raid 5, although the process from 0 to 5 would be very similar. https://community.cisco.com/t5/data-center-documents/cimc-expanding-virtual-drive-on-12gb-sas-controller-by-adding/ta-p/3165778   As noted in my other post, you have to make sure you have at least an application data level backup in case  you run into issues, and have to recreate the raid volumes, reinstall, restore...   Kirk...   ...

This a little bit more complicated than just a standard N5K due to the additional UCSM layer. You can create backups, which for 'logical' is just an XML file that contains the various pools, service profiles   Full state —A binary file that includes a snapshot of the entire system. You can use the file generated from this backup to restore the system during disaster recovery. This file can restore or rebuild the configuration on the original fabric interconnect, or recreate the configuration on a different fabric interconnect. You cannot use this file for an import.   All configuration —An XML file that includes all system and logical configuration settings. You can use the file generated from this backup to import these configuration settings to the original fabric interconnect or to a different fabric interconnect. You cannot use this file for a system restore. System configuration —An XML file that includes all system configuration settings such as usernames, roles, and locales. You can use the file generated from this backup to import these configuration settings to the original fabric interconnect or to a different fabric interconnect. You cannot use this file for a system restore.   Logical configuration —An XML file that includes all logical configuration settings such as service profiles, VLANs, VSANs, pools, and policies. You can use the file generated from this backup to import these configuration settings to the original fabric interconnect or to a different fabric interconnect. You cannot use this file for a system restore.   You can connect to the nxos layer on the FIs and do a show run,,, but the nxos layer on FIs is not something you can general enter the saved config commands back into.   Kirk... ...

Just to confirm, you have hit the <cntl> + M during post, for the megaraidSR config, and actually created a raid 1 virtual drive? I've seen your exact same message for a new server out of the box that has no config for the embedded megaSR controller completed yet.   Kirk... ... View more

You cannot mix those models of servers as converged storage nodes, as they have very different configurations for storage (i.e. 24 drives vs 10. In later versions, you can mix M4/M5 units within the same line (i.e. 220, 240).   Kirk... ... View more

Jumbo frames for NFS or iSCSI is generally a best practice, unless some interfaces along the way don't have jumbo frames supported.  iSCSI is no different than any other type of TCP/Ethernet traffic, in terms of troubleshooting drops.

Any chance you could borrow the dual 1600 watt PSUs from the other unit temporarily to test? Testing the 'problem' unit with different model PSUs, might help rule in/out if the unit has a problem power backplane, vs some odd firmware issue.  If you have the same issue with the 1600watt PSUs, then I would tend to suspect power backplane. I checked our ticket system, and don't see other cases besides yours with this problem, so it may just be one off hardware issue.   Kirk... ... View more

Definitely need to open a TAC case on that. I would want to take a look at the logs. I am assuming the 2 PSUs are exactly the same PID? Both AC sources are the same (i.e.110 vs 220 )?   Any GPUs installed?   What HUU/firmware version?   Thanks, Kirk... ... View more

Greetings. If you are referring to the embedded 'software raid/MegaRaid_SR', then no, ESXi does not support it, and you won't be able to make it work.  You can leave the drives in jbod/AHCI mode, and then esxi will see the individual drives, albeit in a non-redundant config. I would also suspect you would have issues with CPU support when trying to use the newer CPUs with the old OS.   Kirk...   ... View more
