Upgrade Dell PowerFlex to v3.6.x

Upgrade systems with more than 512 SDCs, or configure LIA LDAP in large systems

During nondisruptive upgrades, LIA LDAP configuration, and other actions in large-scale systems, the PowerFlex Gateway constantly requests status updates from all the nodes, even if the operations on those nodes are still pending or have already been completed. This scenario can affect PowerFlex Gateway performance. These recommendations can prevent such performance issues.

1. Create IP address ignore lists in the gatewayUser.properties file.
   1. Using a text editor, open the gatewayUser.properties file, located in the following directory on the PowerFlex Gateway server:
      • Windows—C:\Program Files\EMC\ScaleIO\Gateway\webapps\ROOT\WEB-INF\classes\
      • Linux—/opt/emc/scaleio/gateway/webapps/ROOT/WEB-INF/classes
   2. Add a new line containing the property im.ip.ignore.list= for each batch of components that will be ignored during processing. Add a comma-separated list of IP addresses to the property. The first batch to be processed must include MDMs and SDSs, so they should not be included in the first ignore list. Subsequent batches should include all MDMs and up to 512 SDCs (for LIA LDAP configuration, MDMs can also be ignored after the first batch). Comment out the ignore lists for the second, and subsequent, batches, using the # symbol at the beginning of a line. Optionally, for clarity, add comments describing each ignore list.

      # NDU ignore list for batch 1
      # sdc_group_01,sdc_group_02,sdc_group_03,sdc_group_04
      im.ip.ignore.list=<IP_ADDRESSES_SDC_GROUP_1><IP_ADDRESSES_SDC_GROUP_2><IP_ADDRESSES_SDC_GROUP_3><IP_ADDRESSES_SDC_GROUP_4>

      # NDU ignore list for batch 2
      # all_sds,sdc_group_02,sdc_group_03,sdc_group_04
      # im.ip.ignore.list=<IP_ADDRESSES_ALL_SDS><IP_ADDRESSES_SDC_GROUP_2><IP_ADDRESSES_SDC_GROUP_3><IP_ADDRESSES_SDC_GROUP_4>

      # NDU ignore list for batch 3
      # all_sds,sdc_group_01,sdc_group_03,sdc_group_04
      # im.ip.ignore.list=<IP_ADDRESSES_ALL_SDS><IP_ADDRESSES_SDC_GROUP_1><IP_ADDRESSES_SDC_GROUP_3><IP_ADDRESSES_SDC_GROUP_4>

      # NDU ignore list for batch 4
      # all_sds,sdc_group_01,sdc_group_02,sdc_group_04
      # im.ip.ignore.list=<IP_ADDRESSES_ALL_SDS><IP_ADDRESSES_SDC_GROUP_1><IP_ADDRESSES_SDC_GROUP_2><IP_ADDRESSES_SDC_GROUP_4>

      # NDU ignore list for batch 5
      # all_sds,sdc_group_01,sdc_group_02,sdc_group_03
      # im.ip.ignore.list=<IP_ADDRESSES_ALL_SDS><IP_ADDRESSES_SDC_GROUP_1><IP_ADDRESSES_SDC_GROUP_2><IP_ADDRESSES_SDC_GROUP_3>

      Example:

      # NDU ignore list for batch 1
      # sdc_group_01,sdc_group_02,sdc_group_03,sdc_group_04
      im.ip.ignore.list=1.1.25.10,2.2.25.10,1.1.25.103,2.2.25.103,1.1.25.104,2.2.25.104,1.1.25.106,...

      # NDU ignore list for batch 2
      # all_sds,sdc_group_02,sdc_group_03,sdc_group_04
      # im.ip.ignore.list=1.1.90.20,4.4.90.20,3.3.90.20,2.2.90.20,1.1.90.21,4.4.90.21,2.2.90.21,...

      # NDU ignore list for batch 3
      # all_sds,sdc_group_01,sdc_group_03,sdc_group_04
      # im.ip.ignore.list=1.1.90.20,4.4.90.20,3.3.90.20,2.2.90.20,1.1.90.21,4.4.90.21,2.2.90.21,...

      # NDU ignore list for batch 4
      # all_sds,sdc_group_01,sdc_group_02,sdc_group_04
      # im.ip.ignore.list=1.1.90.20,4.4.90.20,3.3.90.20,2.2.90.20,1.1.90.21,4.4.90.21,2.2.90.21,...

      # NDU ignore list for batch 5
      # all_sds,sdc_group_01,sdc_group_02,sdc_group_03
      # im.ip.ignore.list=1.1.90.20,4.4.90.20,3.3.90.20,2.2.90.20,1.1.90.21,4.4.90.21,2.2.90.21,...

   3. Save and close the file.
   4. Restart the PowerFlex Gateway service:
      • Windows—From the Windows Services window, restart the EMC ScaleIO Gateway.
      • Linux—Type the following command:

        service scaleio-gateway restart

2. Run the standard upgrade procedure on the first batch of components.
3. Edit the gatewayUser.properties file described in step 1.
   1. Comment out the first ignore list.
   2. Uncomment the second ignore list.
      Example:

      # NDU ignore list for batch 1
      # sdc_group_01,sdc_group_02,sdc_group_03,sdc_group_04
      # im.ip.ignore.list=1.1.25.10,2.2.25.10,1.1.25.103,2.2.25.103,1.1.25.104,2.2.25.104,1.1.25.106,...

      # NDU ignore list for batch 2
      # all_sds,sdc_group_02,sdc_group_03,sdc_group_04
      im.ip.ignore.list=1.1.90.20,4.4.90.20,3.3.90.20,2.2.90.20,1.1.90.21,4.4.90.21,2.2.90.21,...

   3. Save and close the file.
   4. Restart the PowerFlex Gateway service:
      • Windows—From the Windows Services window, restart the EMC ScaleIO Gateway.
      • Linux—Type the following command:

        service scaleio-gateway restart

4. Run the upgrade or configuration process again for the second batch.
5. If there are more than two batches of components to be processed, edit the gatewayUser.properties file again.
   1. Comment out the second batch of components.
   2. Uncomment the third batch of components.
   3. Save and close the file.
   4. Restart the PowerFlex Gateway service:
      • Windows—From the Windows Services window, restart the EMC ScaleIO Gateway.
      • Linux—Type the following command:

        service scaleio-gateway restart

6. Run the upgrade or configuration process again for the third batch.
7. Repeat the procedures in steps 5 and 6 for the remaining batches.
