-fc_lt Specifies that physical disks with free chunklets less than the number specified are selected. -devid Specifies that physical disks identified by their device IDs be selected for logical disk creation. Device IDs can be specified in a comma-separated list. Device IDs can be displayed by issuing the showpd -i command. -devtype Specifies that physical disks must have the specified device type (FC for Fibre Channel, NL for nearline, SSD for solid state drive) to be used. Device types can be displayed by issuing the showpd command. -rpm Disks must be of the specified speed. Device speeds are shown in the RPM column of the showpd command. The number does not represent a rotational speed for the drives without spinning media (SSD). It is meant as a rough estimation of the performance difference between the drive and the other drives in the system. For FC and NL drives, the number corresponds to both a performance measure and actual rotational speed. For SSD drive, the number is to be treated as relative performance benchmark that takes into account in I/O per second, bandwidth and the access time. NOTE: Disks that satisfy all of the specified characteristics are used. For example -p -fc_gt 60 -fc_lt 230 -nd 2 specifies all the disks that have greater than 60 and less than 230 free chunklets and that are connected to node 2 through their primary path. SPECIFIERS Specifies the name of the virtual volume, using up to 31 characters, that you are enlarging. RESTRICTIONS • Access to all domains is required to run this command. • Option -pct can only be used if option -szu is used. • Options -pct and -szs cannot be used in the same instance of issuing the growaldvv command. • One or more of the -szu, -sza, and -szs options must be specified. • If enlarging either the administration or snapshot space on the VV and both administration and snapshot space are zero MB, the administration and snapshot space must be enlarged together. Both, the -sza and -szs options must be specified on the command line. Specifying -sza or -szs alone is invalid. • If the volume being enlarged has snapshot data space and snapshot administration space with sizes of 0 bytes, the -sza and -szs options must be specified together. • This command cannot be used to grow a volume in such a way that a volume that currently only has logical disks of a particular device type (Fibre Channel, nearline, or solid state drive) will have logical disks of multiple device types after the grow operation. If a virtual volume currently has logical disks of multiple device types, it is possible to grow the volume using logical disks of any device type. Use showpd to see the device types of physical disks in the system. 174 Grow Commands
