HP Serviceguard Storage Management Suite A.03.00 Release Notes

What’s New with Veritas Volume Manager (VxVM)
The following VxVM features and enhancements are supported in the SG SMS version A.03.00
for HP-UX 11i v3 bundles:

mounted on it.

setattr command with the recoveryoption keyword to configure I/O throttling for
DMP.

paths for the devices in an enclosure.

known to DMP, subpaths of an enclosure, or subpaths through an array port or pwwn.
