period of time.
This can prevent other processes/tasks from running and can cause the background
internode comms processing to be delayed, resulting in the erroneous belief that one
of the other nodes has failed. This is resolved and it prevents the CPU from being held
for an excessive amount of time while traversing the meta data tables during snapshot
removal.

base volumes belonging to a CPG are listed.

Because of this, HP recommens that the backslash (“\”) character be not used in
passwords.

using the FCIP protocol uses a domain RSCN to report when the FCIP connection
comes back online, the HP 3PAR storage system could not detect the RCFC link coming
online and a command had to be issued to bring the link back online. This was because
the InForm OS was not processing domain RSCNs. This is resolved by handling domain
RSCNs as well as other kinds of RSCN such as area and fabric RSCNs.
