Any application using an EqualLogic top-tier device will not require any further intervention.
Disabling Active Management
If you answered No in step 4, active management remains disabled until you explicitly enable it. To enable active management at this point,
run eqlconfig --mpio and accept the default to enable:
======================================================================
Active Migration in Progress
======================================================================
You can choose to end migration and enable active MPIO and iSCSI
session management, abort active migration and leave MPIO disabled,
or just quit eqlconfig immediately, making no changes.
Consult the user guide for further instructions.
Choose action (Enable/Abort/Quit) [Enable]:
• If you choose the default action (Enable), active management of MPIO and iSCSI sessions will begin.
• If you choose Abort, MPIO will be disabled and active migration will be canceled.
• If you choose Quit, no change will be made. Running eqlconfig --mpio will present this same dialog again.
Enabling Storage Cluster Support
To enable storage cluster support, HIT/Linux must be compatible with the High Availability Add-On for RHEL 6 and 7 and the SLES 12 for
storage clusters. There is not much interaction between the clustering software and HIT/Linux.
Cluster Logical Volume Manager
The Cluster Logical Volume Manager (CLVM), part of the Resilient Storage Add-On, is supported. If you followed all LVM setup
instructions, you do not need to take special action when performing a fresh installation or provisioning new storage.
To migrate an existing CLVM node to start using HIT/Linux, follow the migration instructions for LVM in Logical Volume Manager
Considerations.
NOTE:
Although not strictly required, Dell recommends temporarily fencing the node during the migration process to
reduce the possibility of affecting the running cluster on other nodes.
