Dell PowerFlex Appliance with PowerFlex 3.x Administration Guide

Configuring SDCs to use authentication

Use this procedure to configure all the SDCs for authentication.

1. SSH to the VMware ESXi host using the provided credentials.
2. List the hosts current scini parameters esxcli system module parameters list, type -m scini | grep Ioctl.

   IoctlIniGuidStr                      string  10cb8ba6-5107-47bc-8373-5bb1dbe6efa3  Ini Guid, for example: 12345678-90AB-CDEF-1234-567890ABCDEF
   
   IoctlMdmIPStr                        string  172.16.151.40,172.16.152.40           Mdms IPs, IPs for MDM in same cluster should be comma separated. To configure more than one cluster use '+' to separate between IPs.For Example: 10.20.30.40,50.60.70.80+11.22.33.44. Max 1024 characters
   
   IoctlMdmPasswordStr                  string                                        Mdms passwords. Each value is <ip>-<password>, Multiple passwords separated by ';' signFor example: 10.20.30.40-AQAAAAAAAACS1pIywyOoC5t;11.22.33.44-tppW0eap4cSjsKIcMax 1024 characters
   

   NOTE:The third parameter, IoctlMdmPasswordStr is currently empty.
3. Using esxcli, configure the driver with the existing and new parameters. For specifying multiple IP address here, use a semi-colon (;) between the entries, as shown in the following example:

   esxcli system module parameters set -m scini -p "IoctlIniGuidStr=10cb8ba6-5107-47bc-8373-5bb1dbe6efa3 IoctlMdmIPStr=172.16.151.40,172.16.152.40  IoctlMdmPasswordStr=172.16.151.40-AQAAAAAAAAA8UKVYp0LHCFD59BrnExNPvKSlGfLrwAk;172.16.152.40-AQAAAAAAAAA8UKVYp0LHCFD59BrnExNPvKSlGfLrwAk"

   NOTE:The spaces between the Ioctl parameter fields and the opening/closing quotes. The above is entered on a single line.
4. Now the SDC configuration is ready to be applied. On VMware ESXi nodes a reboot is necessary for this to happen. If the SDC is a hyperconverged node, proceed with step 5. Otherwise, skip to step 8.
5. For hyperconverged nodes, use PowerFlex or the scli tool to place the corresponding SDS into maintenance mode.
6. If the SDS is also the cluster primary MDM, switch the cluster ownership to a secondary MDM and verify cluster state before proceeding, type: scli --switch_mdm_ownership --mdm_name <secondary MDM name>
7. Once the cluster ownership has been switched (if needed) and the SDS is in maintenance mode, the SVM may be powered down safely.
8. Place the ESXi host in maintenance mode. If workloads need to be manually migrated to other hosts, have those actions performed now prior to maintenance mode being engaged.
9. Reboot the ESXi host.
10. Once the host has completed rebooting, remove it from maintenance mode and power on the SVM (if present)
11. Take the SDS out of maintenance mode (if present).
12. Repeat steps 1 through 11 for all VMware ESXi SDC hosts.
