For example: sasmgr -N get_info -D /dev/sasd0 -q raid When this option is specified for some commands, it enables you to specify the persistent device file as input to a qualifier. For some commands, when this option is specified, the output will display persistent device file information. If the -N option is not specified, sasmgr will accept and display only legacy device file information. This provides backward compatibility with previous versions of HP-UX. For more information on persistent device files in HP-UX 11i v3, see the intro(7) manpage. The sasmgr Command Set A command is defined by a set of qualifiers. Attributes are specified with the -q option. All keywords are case-sensitive. The following commands are recognized by sasmgr. add One of the following sets of qualifiers must be specified with the add command: • raid • level • enc_bay • size • rebuild_rate Use this set of qualifiers to create a RAID volume with the specified RAID level, volume size and physical disks. The value specified for the level qualifier determines the RAID level for the volume. For example, -q level=1 specifies that a RAID 1 volume should be created. If the physical disks in a RAID volume are different sizes, then some disk space will be wasted. Volume expansion is not supported; once a volume has been created, its size cannot be increased. If the size qualifier is not specified, then the volume is created with a maximum possible size based on the size of the physical disks specified. If the rebuild_rate qualifier is not specified, then the default rebuild rate of 20% will be used for the volume. If the -f option is not specified, sasmgr displays a warning message before continuing the command. Otherwise, it suppresses the warning and executes the command. This command requires superuser privileges. See "Security Restrictions" (page 68). • raid • spare • enc_bay Use this set of qualifiers to add a global spare disk. The global spare disk is used whenever a physical disk in any RAID volume on the controller fails. The size of the disk specified should be greater than the size of at least one of the physical disks in the volume. If the -f option is not specified, sasmgr displays a warning message before continuing the command. Otherwise, it suppresses the warning message and continues executing the command. This command requires superuser privileges. See "Security Restrictions" (page 68). 54 Configuring and Troubleshooting the Controller Online
