VMKernel system properties and commands for configuring properties of the kernel core system and related system services.

core

adapter

  • list
List all the SCSI Host Bus Adapters on the system.
  • esxcli storage core adapter list
  • rescan
Rescan SCSI HBAs to search for new Devices, remove DEAD paths and update path state. This operation will also run an claim operation equivalent to the claimrule run command and a filesystem rescan.
  • esxcli storage core adapter rescan OPTIONS
OPTIONS
 -A|--adapter=<str>    Select the adapter to use when rescanning SCSI
                       adapters. This must be a SCSI HBA name as shown in the
                       adapter list command. This cannot be used with the
                       --all option
 -a|--all              Indicate the rescan should rescan all adapters instead
                       of a specific one.
 -S|--skip-claim       By default after an add operation a claiming session
                       is run to find new devices and have them be claimed by
                       the appropriate Multipath Plugin. Passing this flag
                       will skip that claiming session.
 -F|--skip-fs-scan     This option is deprecated as no filesystem scan is
                       performed by default
 -t|--type=<str>       Specify the type of rescan to perform. Available types
                       are
                           add: Perform rescan and only add new devices if
                       any.
                           all: Perform rescan and do all opertaions (this is
                       the default action.)
                           delete: Perform rescan and only delete DEAD
                       devices.
                           update: Rescan existing paths only and update path
                       states.

capabilities

  • list
List the capabilities of the SCSI HBAs in the system.
  • esxcli storage core adapter capabilities list

device

  • list
List the devices associated with HBAs.
  • esxcli storage core adapter device list

stats

  • get
List the SCSI stats for the SCSI Host Bus Adapters in the system.
  • esxcli storage core adapter stats get

claiming

  • autoclaim
Control the automatic PSA (path/device) claiming code allowing the disabling of the automatic claiming process or re-enabling of the claiming process if it was previously disabled. By default the automatic PSA claiming process is on and should not be disabled by users unless specifically instructed to do so.
  • esxcli storage core claiming autoclaim OPTIONS
OPTIONS
 -c|--claimrule-class=<str>
                       Indicate the claim rule class to use in this operation
                       [MP, Filter, VAAI, all].
 --enabled=<bool>      Set the autoclaiming enabled state for a givenPSA plugin
                       type in the VMkernel. Default is to have this process
                       enabled. This should not be changed by users unless
                       specifically instructed to do so. (required)
 -w|--wait             If the --wait flag is provided then the autoclaim enable
                       will wait for paths to 'settle' before running the claim
                       operation.  This means that the system is reasonably sure
                       that all paths on the system have appeared before enabling
                       autoclaim.
  • reclaim
Attempt to unclaim all paths to a device and then run the loaded claimrules on each of the paths unclaimed to attempt to reclaim them.
  • esxcli storage core claiming reclaim OPTIONS
OPTIONS
 -d|--device=<str>     Reclaim requires the name of a device on which all paths
                       will be unclaimed and then reclaimed. (required)
  • unclaim
1) Unclaim a path or set of paths, disassociating them from a PSA plugin. NOTES: It is normal for path claiming to fail especially when unclaiming by plugin or adapter. Only inactive paths with no I/O will be able to be unclaimed. Typically the ESXi USB partition and devices with VMFS volumes on them will not be unclaimable. Also NOTE unclaiming will not persist and periodic path claiming will reclaim these paths in the near future unless claim rules are configured to mask the path.
2) Detach a (set of) filter(s) from one or more devices.
  • esxcli storage core claiming unclaim OPTIONS
OPTIONS
 -A|--adapter=<str>    If the --type paramter is 'location' this value indicates
                       the name of the host bus adapter for the paths you wish to
                       unclaim. This parameter can be omitted to indicate
                       unclaiming should be run on paths from all adapters.
 -C|--channel=<long>   If the --type parameter is 'location' this value indicates
                       the value of the SCSI channel number for the paths you
                       wish to unclaim. This parameter can be omitted to indicate
                       unclaiming should be run on paths with any channel number.
 -c|--claimrule-class=<str>
                       Indicate the claim rule class to use in this operation
                       [MP, Filter].
 -d|--device=<str>     If the --type parameter is 'device' attempt to unclaim all
                       paths to a specific device (for multipathing plugins) or
                       unclaim the device itself (for filter plugins). NOTE. For
                       paths, if there are any active I/O operations on this
                       device, at least 1 path will fail to unclaim.
 -D|--driver=<str>     If the --type parameter is 'driver' attempt to unclaim all
                       paths provided by a specific HBA driver.

                       the value of the SCSI Logical Unit Number (LUN) for the
                       paths you wish to unclaim. This parameter can be omitted
                       to indicate unclaiming should be run on paths with any
                       Logical Unit Number. If passed, this value must not be
                       higher than the value of the advanced config option
                       /Disk/MaxLUN
 -m|--model=<str>      If the --type parameter is 'vendor' attempt to unclaim all
                       paths to devices with specific model info (for
                       multipathing plugins) or unclaim the device itself (for
                       filter plugins). NOTE. For paths, if there are any active
                       I/O operations on this device, at least 1 path will fail
                       to unclaim.
 -p|--path=<str>       If the --type parameter is 'path' attempt to unclaim a
                       specific path given its path UID or runtime name.
 -P|--plugin=<str>     If the --type parameter is 'plugin' attempt to unclaim all
                       paths on for a given multipath plugin OR all devices
                       attached to a filter plugin.
 -T|--target=<long>    If the --type paramter is 'location' this value indicates
                       the value of the SCSI target number for the paths you wish
                       to unclaim. This parameter can be omitted to indicate
                       unclaiming should be run on paths with any target number.
 -t|--type=<str>       Indicate the type of unclaim you wish to perform. Valid
                       values for this paramter are  [location, path, driver,
                       device, plugin, vendor] (required)
 -v|--vendor=<str>     If the --type parameter is 'vendor' attempt to unclaim all
                       paths to devices with specific vendor info (for
                       multipathing plugins) or unclaim the device itself (for
                       filter plugins). NOTE. For paths, if there are any active
                       I/O operations on this device, at least 1 path will fail
                       to unclaim.
