Erase UCS to Factory Defaults

Here is the commands needed to erase the config on the UCS:

UCS# connect local-mgmt

UCS(local-mgmt)# erase configuration

All UCS configurations will be erased and system will reboot. Are you sure? (yes/no): yes

How To Change the IP Address of Fabric Interconnects

To change IP for fabric interconnects, login to either one via console:

1. UCS-A# scope fabric-interconnect a
2. UCS-A /fabric-interconnect # set out-of-band ip <management IP for FI> netmask <subnet mask> gw <default gateway>
3. Repeat for the second fabric interconnect.

To change the virtual IP used for system management, this should be in the same VLAN as the individual fabric interconnect IPs:

1. UCS-A# scope system
2. UCS-A /system # set virtual-ip <management IP>

Finally check to see that there are no errors, then actually commit if everything checks out:

1. UCS-A# commit-buffer verify-only
2. UCS-A# commit-buffer

I am going to make this one short and sweet.

On a reboot, hosts that have access to RDM LUNs can take a LONG time to reboot. In order to correct to correct this we can set the hosts to have the LUNs perennially reserved.

The only way to set this is by typing(sorry no GUI fix).

In esxcli we see,

esxcli storage core device setconfig -d naa.12345671234982734987 –perennially-reserved=true

(Above I just started typing random numbers, but you get the idea)

In general though you are going to have more than one host in a cluster that have access to the same RDMs. As usual PowerCLI to the rescue.

This script will pull the RDMs from a specific VM and set the Perennially Reserved flag for all the hosts in the cluster.http://www.vnoob.com/2015/12/set-perennially-reservation-with-powercli/
