Upgrading in an HP Continuous Access EVA environment
The following restrictions apply when upgrading to VCS v4.001 on EVA3000/5000 storage systems
running Continuous Access EVA:
• The upgrade process should be c ompleted within one week (168 hours). The time window begins
with the upg rade of the first storage system. It concludes when all stora ge systems with a direct or
indirect Continuous Access relationship to the first storage system have been upgraded.
• Ensure that all storag e systems involved in a DR relationship are fully functional with no failed
hardware.
• When using multiple Continuous Access relationships, ma ke sure the following conditions are met:
• Not more than two VCS versions (either v3.028 or v4.001) are running.
• All EVA 4000/6000/8000 storage systems must be running only one version of XCS (V5.030
or later).
• If you need to update both VCS an d XCS, do n ot attempt to upgrade both simultaneously.
Complete the upgrade one family of firmware before upgrading the other.
• Suspend DR group replication for the duration of the upgrade process on the destination, even if
the intersite links are not available.
• Do not create or delete D R groups or add members or remove members from DR groups when
any storage system in the Continuous Access relationship is still on VCS 3.028 and others are
on VCS v4.001.
A code load of one controller forces both controllers on a storage system to reboot. If the controller being
upgraded is used as a destination for replication I/O, the source controller logs new I/O while the
destination controller reboots. After completing the firmware upgrade of the destination then resume
the replication to allow the controller to perform a m erge. Wait for the m erge to conclude after a code
load, or wait three minutes—whichever is longer—before performing the c od e load on any other storage
system in the relationship.
