job (EVM job)
A file created by EVM that represents a user request to perform a task or series of tasks. For
example, the EVM job named stor1_backup_daily_sales might:
1. Replicate a storage unit by the clone method to create BCV units
2. Mount the BCV units on a server
3. Start the tape backup of the BCV units
EVM jobs are created by using the EVM Job Add page of the GUI. Jobs can be run from either
the GUI, via the EVM Command Line, from script files, or from a scheduler.
LUN
Logical Unit Number. In a storage system, the value that identifies logical storage units of a
SCSI target device.
management appliance
A host-independent server product designed to connect directly to the SAN fabric. The
management appliance provides a centralized point for managing and monitoring SAN
elements, including HP switches and storage arrays.
Open SAN Manager (OSM) software installed on the appliance provides a GUI interface for
accessing the monitored SAN environment. The OSM also provides a launch site for a variety
of value-added HP OpenView applications and provides navigation links to directly manage
storage components on the SAN.
mount point
In UNIX, the directory to use for mounting a device. For example, the /usr directory could be
the mount point for the disk device /dev/dsk/c0t1d0s6.
node
A generic term for an addressable unit, such as a computer or peripheral device attached to a
network. In EVM, an EVM-enabled computer that is connected to the EVM network.
RAID
Redundant Array of Independent Disks. A set of techniques for configuring and using an array
of physical disks to provide fault tolerance and increase performance of a storage system.
SAN
Storage Area Network. A dedicated, high-speed sub-network of storage devices that are
available to servers on a local area network (LAN) or wide area network (WAN). As storage
devices are added to the SAN, they become accessible to the servers in the larger network.
