pub struct System {
    pub id: String,
    pub name: String,

    pub status_info: String,
    pub fw_version: String,
    pub read_cache_pct: i8,
    pub mode: SystemMode,

}

Represent a storage system. Examples:

• A hardware RAID card, LSI MegaRAID

• A storage area network (SAN), e.g. EMC VNX, NetApp Filer

• A software solution running on commodity hardware, targetd, Nexenta

• A Linux system running NFS service

Fields

id: String

Identifier.

name: String

Human friendly name.

status: u32

System status stored in bitmap. Valid status value are:

• System::STATUS_UNKNOWN
• System::STATUS_OK
• System::STATUS_ERROR
• System::STATUS_DEGRADED
• System::STATUS_PREDICTIVE_FAILURE
• System::STATUS_OTHER

if (s.status & System::STATUS_OK) == 0 {
    println!("System {}/{} is not healthy", s.name, s.id);
}

status_info: String

Additional message for status.

fw_version: String

Firmware version.

read_cache_pct: i8

Read cache percentage of the system. Valid values are:

• >0 and < 100 means only a part of whole cache are used for read.
• 0 means no read cache.
• 100 means all cache are used for read.
• System::READ_CACHE_PCT_NO_SUPPORT means no support.
• System::READ_CACHE_PCT_UNKNOWN means plugin failed to detect this value.

mode: SystemMode

System mode, currently only supports hardware RAID cards.

Methods

impl System

const READ_CACHE_PCT_NO_SUPPORT: i8

READ_CACHE_PCT_NO_SUPPORT: i8 = -2

Plugin does not support querying read cache percentage.

const READ_CACHE_PCT_UNKNOWN: i8

READ_CACHE_PCT_UNKNOWN: i8 = -1

Plugin failed to query read cache percentage.

const STATUS_UNKNOWN: u32

STATUS_UNKNOWN: u32 = 1

const STATUS_OK: u32

STATUS_OK: u32 = 1 << 1

System is up and healthy.

const STATUS_ERROR: u32

STATUS_ERROR: u32 = 1 << 2

System is in error state.

const STATUS_DEGRADED: u32

STATUS_DEGRADED: u32 = 1 << 3

System is degraded.

const STATUS_PREDICTIVE_FAILURE: u32

STATUS_PREDICTIVE_FAILURE: u32 = 1 << 4

System has protential failure.

const STATUS_OTHER: u32

STATUS_OTHER: u32 = 1 << 5

Vendor specific status.
