Apêndice B.22 do Gerenciador de Volume Lógico do AIX de A a Z: Resolução de Problemas e Comandos a partir do ano 2000 descreve o seguinte:
lqueryvg - An object file command that queries the attributes of a volume group. Usage: lqueryvg [-g VGID] [-p PVname] [-N] [-s] [-F] [-n] [-c] [-D] [-a] [-l] [-P] [-A] [-v] [-t] -g VGID The VGID of the volume group to query. -p PVname The name of the physical volume that contains the VGID. -N Returns the maximum number of logical volumes allowed in the volume group. -s Returns the physical partition size. -F Returns the number of free physical partitions in the volume group. -n Returns the current number of logical volumes in the volume group. -c Returns the current number of physical volumes in the volume group. -D Returns the total number of VGDAs for the volume group. -a Returns all the static attributes for the volume group ( ). -l Returns each LVID, logical volume name and state for each logical volume in the volume group. -P Returns each PVID, number of VGDAs and state for each physical volume in the volume group. -A Returns all attributes for the volume group (static attributes, logical volume details and physical volume details). -v Used only with the -p PVName flag to return the VGID from that physical volume. -t Includes the tags with the output for the above options.
Há também uma nota perto do final da seção 2.6.7 dizendo:
Essentially, the low-level commands prefixed with l simply act as parsers and front-ends onto the LVM API calls. To gain a good understanding of these commands’ capabilities, one may look up the relevant API call, for example, lvm_queryvgs for lqueryvgs. These calls are listed in the AIX Version 4.3 Technical Reference: Kernel and Subsystems Technical Reference, Volume 1, SC23-4163. Recall, however, that BigVG functionality will not be documented by IBM.
