Other Issues - HP 201723-B21 - StorageWorks Modular SAN Array 1000 Hard Drive Release Note

MSA1x00 issues
• MSA LUN name between Array Configuration Utility (ACU) and SSCM does not match: LUN names
created by the MSA ACU and SSCM do not match when displayed. The ACU LUN name is partly
shown in SSCM as LUN identification.
MSA hardware provider memory leak: The HP MSA hardware provider installed with SSCM has
•
a memory leak that may increase during VDS operations. To reclaim lost memory, close SSCM
to unload the MSA hardware provider. See the HP website for updates to the HP MSA hardware
provider.
Hosts connecting to MSA storage subsystems may not be discovered by SSCM during fabric changes:
•
When MSA responds to a fabric event (such as zoning changes) the HBA agent software takes
some time to discover the MSA storage subsystem. When the system is in this state, and SSCM is
launched, it may not discover the host because the HBA agent software is still busy.
Workaround: If this occurs, either relaunch SSCM after a few minutes or refresh the server list,
and/or manually add the server.
Switch issues
• SSCM and switch passwords: If the switch password is set up or updated using SSCM, SSCM re-
members the password and does not prompt for one when a switch operation is initiated. However,
if you set up or change the password in another application (such as QuickTools), SSCM cannot
retrieve the switch information when launched. SSCM shows the default generic switch name, and
any switch operation that you request will prompt for the password.
• SSCM shows switch zoning information as Unknown for vendor and device type: SSCM uses the
switch zoning component Fibre Channel worldwide port name (WWPN) to match the vendor and
device type. If the switch zoning is not WWPN based, it shows the information as Unknown in
the Switch Zoning Information dialog box.

Other issues

Graphics for the MSA and EVA are not accurate: The storage subsystem graphics in the Manage
•
Storage Subsystem dialog box are intended as an abstract representation of the MSA and EVA
storage subsystems and their enclosures and drives. The graphic images do not reflect the physical
layout of the subsystems.
LUN multipath information: A LUN's multipath information is available only if the LUN is presented
•
to the management host on which the VDS hardware provider and SSCM are installed and running.
Workaround: To obtain multipath information for LUNs presented to other hosts, issue the hpdsm
devices command from either the EVA DSM command line interface (CLI) or the MSA DSM CLI
on that host.
• To launch the EVA DSM, select Start > Programs > Hewlett-Packard > EVA DSM > HPDSM
CLI.
• To launch the MSA DSM, select Start > Programs > Hewlett-Packard > MSA DSM > HPDSM
CLI.
• SSCM startup: SSCM may take several minutes to start up. The size of your SAN and the config-
uration of your storage directly affects the startup time.
SSCM uses an Ethernet broadcast mechanism to discover the hosts and their HBAs in the SAN. If
there are a large number of hosts in the network responding to this broadcast, the host discovery
process may take some time to complete.
