Dell PowerFlex Appliance with PowerFlex 4.x Administration Guide

Configure storage data client to use authentication

Perform this procedure to configure the storage data clients for authentication.

1. Using SSH log in to the VMware ESXi host using the provided credentials.
2. Type esxcli system module parameters list -m scini | grep Ioctl to list the hosts current scini parameters:

   IoctlIniGuidStr                      string  d30ff770-b64c-40b5-a341-58d18927e523                             Ini Guid, for example: 12345678-90AB-CDEF-1234-567890ABCDEF
   IoctlMdmIPStr                        string  192.168.151.20,192.168.152.20,192.168.153.20,192.168.154.20  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 empty.
3. Using ESXCLI, configure the driver with the existing and new parameters. To specify multiple IP addresses, use a semicolon (;) between the entries, as shown in the following example. Additional data IP addresses, data3, and data4 can be used, if required.

   esxcli system module parameters set -m scini -p "IoctlIniGuidStr=10cb8ba6-5107-47bc-8373-5bb1dbe6efa3 IoctlMdmIPStr=192.168.151.20,192.168.152.20 IoctlMdmPasswordStr=192.168.151.20- AQAAAAAAAAA8UKVYp0LHCFD59BrnExNPvKSlGfLrwAk;192.168.152.20-AQAAAAAAAAA8UKVYp0LHCFD59BrnExNPvKSlGfLrwAk bBlkDevIsPdlActive=1 blkDevPdlTimeoutMillis=60000"

   NOTE:There are spaces between Ioctl parameter fields and the opening quotes. The example is entered on a single line.
4. Reboot the VMware ESXi nodes.
   The SDC configuration is applied.

   If the SDC is a PowerFlex hyperconverged node, go to the next step. For other nodes, continue to step 8.

5. For PowerFlex hyperconverged nodes, use the scli tool to place the corresponding SDS into maintenance mode.
6. If the SDS is also the cluster primary MDM, switch cluster ownership to a secondary MDM and verify cluster state before proceeding, type scli --switch_mdm_ownership --mdm_name <secondary MDM name>.
7. Power off the SVM once the cluster ownership is switched (if needed) and the SDS is in maintenance mode.
8. Manually migrate the workloads to the other hosts if required, and place the VMware ESXi host in maintenance mode.
9. Reboot the VMware 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 the maintenance mode (if present).
12. Repeat this procedure for each VMware ESXi SDC host.

Windows (from within a PowerShell prompt):
C:\Program Files\EMC\scaleio\sdc\bin\drv_cfg --set_mdm_password --ip <MDM IP> --port 6611 --password <secret>

Linux:
/opt/emc/scaleio/sdc/bin/drv_cfg --set_mdm_password --ip <MDM IP> --port 6611 --password <secret> --file /etc/emc/scaleio/drv_cfg.txt
