Table 82 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 vdisk 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.
storage-
overcommit-
enabled
string Not applicable.
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 vdisks that the system supports.
max-luns uint32 Number of LUNs that the system supports.
max-owned-
arrays-per-
controller
uint32 Number of vdisks that each controller supports.
max-storage-
pools-per-
controller
uint32 Not applicable.
max-capi-arrays uint32 Same as max-vdisks.
max-chunk-size uint32 Maximum chunk size for vdisks.
min-chunk-size uint32 Minimum chunk size for vdisks.
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. The default is 1 percent.
vdisk-metadata-
size-perdisk-
blocks
uint32 Amount of space reserved on a disk for vdisk metadata, in 512-byte blocks.
vdisk-metadata-
size-blocks
uint32 Amount of metadata, in blocks, stored on each disk.
max-host-
groups-per-
storage-pool
uint32 Not applicable.
max-hosts-per-
host-group
uint32 Not applicable.
