Enterprise Virtual Array (EVA) on HP-UX 11i v3

Summary of Change

What is New for Customers Migrating from HP-UX 11i v1 September 2005?

When using EVA snapclones and snapshots, each snapsclone or snapshot of a given device results in a new unique LUN WWID (world-wide identifier). On HP-UX 11i v3 (11.31), each new LUN WWID is created without old ones being removed. Over time, this can cause memory to be filled by the WWIDs. There is no tool to monitor this issue, but a reboot and cleanup can free the memory.

For more information, see the HP StorageWorks EVA Replication Consolidated Release Notes XCS 6.0x (see the following “Documentation” section).
