Veritas Volume Manager 5.0.1 Release Notes, HP-UX 11i v3, First Edition, November 2009

— New Log File Location for DMP Events
The new log file for DMP events is the /var/adm/vx/dmpevents.log file. For
backward compatibility, the previous log file, /etc/vx/dmpevents.log, is
symbolically linked to the /var/adm/vx/dmpevents.log file.
— Extended Device Attributes Displayed in the vxdisk list Command
The vxdisk list command now displays extended device attributes, such as hardware
mirrors, for certain arrays.
— Displaying the use_all_paths Attribute for an Enclosure
You can obtain the value of the use_all_paths attribute of an enclosure to specify
whether DMP must issue I/O requests on both the primary and secondary paths on an
Asymmetric Active/Active (A/A-A) LUN. For more information on the use_all-paths
attribute, see Veritas Volume Manager 5.0.1 Administrator’s Guide.
— Viewing Information about the Array Support Libraries (ASLs) Installed on the
System
The /usr/lib/vxvm/diag.d/vxcheckasl command has been enhanced to provide
information on the following:
◦ ASLs installed in the system
◦ Devices visible to the operating system
◦ All the possible ways in which the ASLs can interact with these devices
— Displaying the Number of LUNs in an Enclosure
The vxdmpadm listenclosure command now displays the number of LUNs in its
default output.
— Displaying LUN serial number
The vxdmpadm getdmpnode command now includes the option -v to display the
LUN serial number along with other information.
— Displaying Host-Based Adaptor (HBA) details
The vxdmpadm getctlr output has been enhanced to display the HBA vendor details
and the Controller ID. For iSCSI devices, the Controller ID is the name based on IQN
or IEEE-format. For Fibre Channel devices, the Controller ID is the WWN. Because the
WWN is obtained from the Event Source daemon, the Controller ID field is blank if the
Event Source daemon is not running.
— New exclude and include Options for the vxdmpadm Command
The vxdmpadm command now includes exclude and include commands to suppress
or unsuppress devices from VxVM, respectively.
The exclude and include commands provides a command-line interface for the
suppress and unsuppress operations, which previously required user interaction.
— New Command for Reporting DMP Node Information
The vxdmpadm command now includes the list command to display information
about a DMP node, including all of the attributes that are set for that DMP node. You
can use the vxdmpadm list command for a specified DMP node, all DMP nodes, all
DMP nodes on the path name or DMP node name, or all DMP nodes in an enclosure.
— Setting Attributes for all Enclosures
The vxdmpadm setattr command now provides the all option for enclosure, array
type, and array name. The all option enables you to set the attributes, iopolicy,
failover_policy, and recoveryoption, on all the specified enclosures.
