3.3 Storage Server Configuration Guidelines

The following guidelines must be observed when planning an online InForm OS update:

■ VLUN for each exported volume must be exported to a defined host on at least two fully

operational paths that span horizontally adjacent storage server nodes (valid pairings are 0

& 1, 2 & 3, 4 & 5, 6 & 7).

■ 3PAR software applications running on the InServ Storage Server must be shut down. 3PAR

Remote Copy must be stopped for all systems running below InForm OS 2.2.3, and no full or

physical copies may be in progress.

■ Ensure that no 3PAR Virtual Copy promotes are in progress. To confirm, check that no

volumes are in the started, cpp state. If any promotes are in progress, wait until the

promote finishes to begin the online update.

■ For systems running Remote Copy below InForm OS 2.2.3, stop the synchronization

processes for the duration of the update by using the following command:

stoprcopy –stopgroups. For systems running InForm OS 2.2.4 with Remote Copy, only

the groups needs to be stopped.

■ During the process of InForm OS upgrades, plan on upgrading both InServ Storage Servers

in the Remote Copy pair within a five week period. The difference in the InForm OS Release

versions cannot be greater than adjoining release levels,. i.e. 2.2.4 and 2.3.1 (all MU

versions are treated as the same OS version).

■ Starting with InForm OS 2.2.2, Remote Copy Ethernet ports must be set to autonegotiate. If

they were changed to 100Mbs full duplex, the links may not start when performing a

software update to InForm OS 2.3.1. The auto-negotiate setting can be changed in advance

of a software update by executing controlport rcip speed auto {value} {n:s:p}.

NOTE: If a host server is powered down during an upgrade from 2.2.x to 2.3.1 the

recommended Host Persona for the type of host that is down should apply, as the

upgrade assigns Host Persona 6 to the server. In some cases, it would prevent the

host from operating correctly, as is the case with HPUX, AIX, and NetApp.
