■ Remote Copy VVs must be the same size on the primary and the secondary system. Earlier
releases of InForm OS allowed the secondary VV in a remote copy group to be larger than
the primary. Check to insure that all volumes in a remote copy group are equal sizes on the
primary and secondary InServ Storage Server.
4.0 Planning Information for Online InForm OS Updates
The host connectivity environment must adhere to the qualified and supported environments
(see the 3PAR InForm OS 2.3.1 Configuration Matrix). 3PAR service representatives will request
this information for review before performing an online update. Relevant details include:
■ Host platform
■ Architecture (i.e. SPARC/x86)
■ OS (version and patch level)
■ DMP software
■ HBA (vendor, model, driver, firmware, and version. Also include FCODE and BIOS level if
booting from InServ Storage Server)
■ Switch (vendor, model and firmware)
■ Information on host software provided by 3PAR is needed. Examples include: 3PAR
Recovery Manager (SQL, Exchange, Oracle), 3PAR VSS Provider, 3PAR MPIO for Microsoft®
Windows®, 3PAR ODM Definition for IBM AIX, 3PAR System Reporter, etc.
■ In addition to verifying the driver/firmware levels match the Configuration Matrix, there
may be host configuration settings that are needed as documented in the 3PAR
Implementation Guides. These settings need to be verified before an online update is
performed.
