Table 122. system-parameters-table properties
Name Type Description
ulp-enabled string Shows true to indicate that the system is using Unified LUN Presentation, which can
expose all LUNs through all host ports on both controllers. The interconnect information
is managed in the controller firmware. ULP appears to the host as an active-active
storage system where the host can choose any available path to access a LUN
regardless of disk group ownership. When ULP is in use, the system's operating/cache-
redundancy mode is shown as Active- Active ULP. ULP uses the T10 Technical
Committee of INCITS Asymmetric Logical Unit Access (ALUA) extensions, in SPC-3, to
negotiate paths with aware host systems. Unaware host systems see all paths as being
equal.
profiles-enabled string Shows whether host profiles are enabled.
• true: Host profiles are enabled.
• false: Host profiles are disabled.
max-ports uint32 Number of host-interface ports in the controller enclosure.
max-drives uint32 Number of disks that the system supports.
max-volumes uint32 Number of volumes that the system supports.
max-vdisks uint32 Number of linear disk groups that the system supports.
max-luns uint32 Number of LUNs that the system supports.
max-owned-arrays-per-
controller
uint32 Number of linear disk groups that each controller supports.
max-storage-pools-per-
controller
uint32 The number of virtual pools that each controller supports.
max-components-per-storage-
pool
uint32 The number of virtual pools that each pool can contain.
max-storage-pool- size string The maximum size of a virtual pool.
max-storage-pool- size-numeric uint64 Unformatted max-storage-pool-size value in blocks.
max-capi-arrays uint32 Same as max-vdisks .
max-chunk-size uint32 Maximum chunk size for disk groups.
min-chunk-size uint32 Minimum chunk size for disk groups.
physical-position-offset uint32 Starting index for physical components (enclosures, disks, etc.) in the storage system.
backoff-percentage uint32 Percentage of disk capacity that is reserved to compensate for minor capacity
differences between disk drives so they can be used interchangeably. This is not
settable by users.
vdisk-metadata-size-perdisk-
blocks
uint32 Amount of space reserved on a disk for metadata, in blocks.
vdisk-metadata-size-blocks uint32 Amount of metadata, in blocks, stored on each disk.
max-host-groups uint32 The number of host groups that the system supports.
max-hosts-per-host-group uint32 The maximum number of hosts that a host group can contain.
max-initiator uint32 The maximum number of initiators that a host can contain.
max-volume-groups-per-
controller
uint32 The maximum number of volume groups that each controller supports.
