4. When an upgrade is paused by using Ctrl+C, if the upgrade is currently upgrading a node, choose one of
these options:
◦ Wait: Allow the currently upgrading node to finish before resetting the cluster constants.
◦ Continue: Continue the upgrade, which cancels the pause.
◦ Abort: Reset the cluster constants and abort the upgrade immediately.
Aborting the cluster upgrade while a node is being updated might result in the drives
being ungracefully removed from the node. If the drives are ungracefully removed,
adding the drives back during an upgrade will require manual intervention by NetApp
Support. The node might be taking longer to do firmware updates or post update
syncing activities. If the upgrade progress seems stalled, contact NetApp Support for
assistance.
Upgrading H610S storage nodes to Element 12.2 (phase 2)
If you are upgrading an H610S series node to Element 12.2 and the node is running a version of Element
earlier than 11.8, the upgrade process involves two phases.
Phase 1, which is performed first, follows the same steps as the standard upgrade to Element 12.2 process. It
installs Element Software and all 5 firmware updates in a rolling fashion across the cluster one node at a time.
Due to the firmware payload, the process is estimated to take approximately 1.5 to 2 hours per H610S node,
including a single cold-boot cycle at the end of the upgrade for each node.
Phase 2 involves completing steps to perform a complete node shutdown and power disconnect for each
H610S node that are described in a required KB. This phase is estimated to take approximately one hour per
H610S node.
After you complete phase 1, four of the five firmware updates are activated during the cold
boot on each H610S node; however, the Complex Programmable Logic Device (CPLD)
firmware requires a complete power disconnect and reconnect to fully install. The CPLD
firmware update protects against NVDIMM failures and metadata drive eviction during future
reboots or power cycles. This power reset is estimated to take approximately one hour per
H610S node. It requires shutting down the node, removing power cables or disconnecting
power via a smart PDU, waiting approximately 3 minutes, and reconnecting power.
Before you begin
• You have completed phase 1 of the H610S upgrade process and have upgraded your storage nodes using
one the standard Element storage upgrade procedures.
Phase 2 requires on-site personnel.
Steps
1. (Phase 2) Complete the power reset process required for each H610S node in the cluster:
If the cluster also has non-H610S nodes, these non-H610S nodes are exempt from phase 2
and do not need to be shut down or have their power disconnected.
a. Contact NetApp Support for assistance and to schedule this upgrade.
b. Follow the phase 2 upgrade procedure in this KB that is required to complete an upgrade for each H610S
node.
