EXAMPLES The following example displays the enlarging of a RAID-5 virtual volume with 3+1 parity ratio named vv01 by 10 GB: cli% growaldvv -szu 10g -t r5 -ssz 4 vv01 NOTES • A volume can be enlarged while I/O is occurring. • When issuing the growaldvv command, the specified options only apply to the newly enlarged sections of the volume. This can result in a VV that has different characteristics in its base and grown sections. • If options were used in the creation of the original virtual volume (createaldvv) that were not the default option values, and not specified in the same manner when issuing the growaldvv command, growaldvv uses the createaldvv default option values. This can result in a virtual volume that has different characteristics in its base and grown sections. • By default, LDs are created using only physical disks with the same device type (by default, the Fibre Channel device type is used). Use the -p devtype NL option or -p -devtype SSD to override this default. Use the showpd command to see the device types of PDs in the system. • If no device type is specified using the -p -devtype option, Fibre Channel is assumed. • This command is only used for a non-provisioned VV. The command growvv should be used instead for a virtual volume that has its user space provisioned from a CPG. • For this command: • KB = 1024 bytes • MB = 1024 KB • GB = 1024 MB growaldvv 175
