Complete the following tasks before upgrading.

• The FluidFS cluster must be at FluidFS version 2.0.7630 or later before upgrading to FluidFS version 3.0.

• When upgrading to V3 “admin” user will not be available anymore, and local “Administrator” must be used instead. Make sure to know its password, Administrator password must be changed up to 24 Hours before the upgrade. To change Administrator password Login to CLI ( Using SSH ) and run the following command :system authentication local-accounts users change-password Administrator

  • CAUTION: The password you set will be required to manage the FluidFS cluster after upgrading to version 3.0. Make sure that you remember this password or record it in a secure location.

• Change the FluidFS cluster name to match the NetBIOS name, if needed. Also, ensure that the FluidFS cluster name is no longer than 15 characters and does not begin with a digit.

• Change the internal subnet to a Class C subnet, if needed.

• Convert user‐defined administrator accounts to local users, if needed.

• Change policies that mount the \\ <client_VIP_or_name>\homes share to mount the \\ <client_VIP_or_name>\ <path_prefix>\ <username> share, if needed.

• Delete local user names that have a period as the last character and re‐create the accounts with a different name, if needed.

• Change the NDMP client port to be in the range 10000–10100, if needed. You must also make the reciprocal change on the DMA servers.

• Stop all NDMP backup sessions, if needed. If an NDMP backup session is in progress during the upgrade, the temporary NDMP snapshot is left in place.

• Open additional ports on your firewall to allow replication between replication partners, if needed.

• Remove parentheses characters from the Comment field for CIFS shares and NFS exports.

• Ensure the NAS volumes do not have the following names (these names are reserved for internal FluidFS cluster functions):

  • .

  • ..

  • .snapshots

  • acl_stream

  • cifs

  • int_mnt

  • unified

  • Any name starting with locker_

• Ensure that at least one of the defined DNS servers is accessible using ping and dig (DNS lookup utility).

• Ensure that the Active Directory domain controller is accessible using ping and that the FluidFS cluster system time is in sync with the Active Directory time.

• Ensure that the NAS controllers are running, attached, and accessible using ping, SSH, and rsync.

• Although the minimum requirement to upgrade is that at least one NAS controller in each NAS appliance must be running, Dell recommends ensuring that all NAS controllers are running before upgrading.

• Ensure that the FluidFS cluster system status shows running.
