system-parameters-table This basetype is used by show system-parameters. Table 80 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. profilesenabled storageovercommitenabled max-ports max-drives max-volumes max-vdisks max-luns max-ownedarrays-percontroller max-storagepools-percontroller max-capi-arrays max-chunk-size min-chunk-size physicalposition-offset backoffpercentage vdisk-metadatasize-perdiskblocks vdisk-metadatasize-blocks max-hostgroups-perstorage-pool max-hosts-perhost-group string string Shows whether host profiles are enabled. • true: Host profiles are enabled. • false: Host profiles are disabled.

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-

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.
