Host Software Upgrades

Before performing the hardware upgrade, software updates to host software may be required for compatibility with

the new system. These updates may include PowerPath, Navisphere Host Agent, Navisphere Server Utility,

Navisphere CLI, admsnap, and others. For a listing of revisions of Navisphere software supported with each FLARE

revision, see the ―Navisphere management software requirements‖ table in the EMC Navisphere Host Agent/CLI

and Utilities Release Notes on EMC Powerlink. For recommended revisions of PowerPath and admsnap refer to E-

Lab™ Navigator on EMC Powerlink.

Special Case Upgrade Paths

Some upgrade paths require special considerations. It is important to obtain the latest version of CAP2, which

contains pre-upgrade checks for many of these situations.

CX3-10c and CX4-120 Upgrades

CX3-10c systems that use SATA for the OS drives may only be upgraded to a CX4-120 with SATA OS drives.

CX4-120 systems that use SATA for the OS drives may not be upgraded. There is NOT a procedure to swap

the SATA drives for the Fibre Channel drives that are required in the larger systems. The CAP2 CRC check will

verify the OS drive type.

Low-cost HBAs in any attached servers (for example, Emulex LP-101) that are supported by the CX3-10c and

CX4-120, but are not supported by the rest of the Dell/EMC family, must be swapped out prior to conversion.

Use E-Lab Navigator to validate the new configuration.

The version of PowerPath bundled with the CX3-10c and CX4-120 is not supported by any other models in the

Dell/EMC family. PowerPath licenses must be purchased prior to the upgrade to the new storage system.

CX3-20f to CX4 Upgrades

The CX3-20f system has six FC front-end ports per SP while the base CX4-240 has only two FC front-end ports per

SP. There cannot be a loss of port count during a conversion. Therefore, an additional FC I/O module is required on

each SP. A FC UltraFlex I/O kit, consisting of a pair of FC I/O modules, must be purchased separately from array

upgrade kit.

Special Considerations for Replication Software

Private LUNs

Private LUNs used by EMC replication software cannot be migrated using LUN migration. These include clone

private LUNs (CPLs) used by SnapView™ clones, write intent log (WIL) LUNs optionally used by

MirrorView™/Synchronous mirrors, and reserved LUNs used by SnapView snapshots, SAN Copy™ incremental

sessions, and MirrorView/Asynchronous mirrors. If CAP2 identifies these as LUNs requiring relocation, they need

to be moved elsewhere, which may involve some disruption and reconfiguration of the replication software that uses

them. CPL and WIL LUNs can be moved with no disruption to clones or synchronous mirrors. Moving LUNs from

the reserved LUN pool requires destruction of all SnapView sessions, MirrorView/Asynchronous mirrors, and SAN

Copy incremental sessions using those reserved LUNs. Full resynchronizations are required for SAN Copy

incremental sessions and MirrorView/Asynchronous mirrors. For information about migrating private LUNs, review

the specialized procedure documented in the CPG.
