Displays dynamically reconfigurable slots, such as hot plug slots, and their characteristics.
The lsslot command displays all the specified hot plug slots and their characteristics. Hot plug slots are the plug-in points for connecting entities that can be added and removed from the system without turning the system power off or rebooting the operating system. The -c flag is required. It specifies the type of hot plug connector, for example, pci for hot pluggable PCI adapters. You can display only the empty, that is, available, hot plug slots with the -a flag, the occupied slots with the -o flag, or a specific slot by using the -s flag. The -l flag can be used to locate the slot associated with specified DeviceName, as listed by the lsdev command.
The output of the lsslot command is dependent on the ConnectorType and the platform on which the command is executed. The characteristics of a slot may include the following:
When the PHBs are listed using the lsslot command, the Device(s) Connected column will display the ODM name of the PHB followed by the ODM names of the devices corresponding to the logical slots underneath the PHB, with all the ODM devices associated with each logical slot displayed on each separate line under the ODM name of the PHB. In case there is no ODM name for the PHB, a blank line will be displayed.
Item | Description |
---|---|
-a | Displays available hot plug slots and their characteristics. Available slots are those slots that do not have a hot plug device connected. This flag is ignored for connector types of slot and phb. |
-c ConnectorType | Displays the slots of the specified ConnectorType. ConnectorType identifies the type of connector. For example, the ConnectorType for a hot plug PCI slot is pci, for logical slots, it is slot and for PHBs, it is phb. This flag is required. |
-F Delimiter | Specifies a single character to delimit the output. The heading is not displayed and the columns are delimited by the Delimiter character. |
-l DeviceName | Displays the characteristics of the slot to which DeviceName is associated. The DeviceName is the logical device name of the device connected to the slot, as listed by the lsdev command. |
-o | Displays the characteristics of the occupied slots. Occupied slots have a hot plug device connected. This flag is ignored for connector types of slot and phb. |
-s Slot | Displays characteristics for the specified Slot. The format of Slot is platform/connector_type dependent. |
The system displays a message similar to the following:
Item | Description | |
---|---|---|
Slot name | Description | Device(s) Connected |
U0.4-P1-I1 | PCI 64 bit, 66MHz, 3.3 volt slot | empty |
U0.4-P1-I2 | PCI 64 bit, 66MHz, 3.3 volt slot | empty |
U0.4-P1-I3 | PCI 64 bit, 66MHz, 3.3 volt slot | empty |
The system displays a message similar to the following:

U0.4-P1-I1 | PCI 64 bit, 33MHz, 5 volt slot | scsi1 |
lsslot -c pci
The system displays a message similar to the following:
Item | Description | |
---|---|---|
Slot name | Description | Device(s) Connected |
U0.4-P1-I1 | PCI 64 bit, 33MHz, 3.3 volt slot | empty |
U0.4-P1-I2 | PCI 64 bit, 33MHz, 3.3 volt slot | scsi0 |
U0.4-P1-I3 | PCI 64 bit, 33MHz, 3.3 volt slot | unknown |
U0.4-P1-I5 | PCI 64 bit, 33MHz, 3.3 volt slot | empty |
Slots that have unknown in the Device(s) Connected column have a device connected to the slot, but the device isn't in the ODM customized device (CuDv) database. This can be due to the device having been newly added but not configured yet, deleted with the rmdev -d command, or the system may not be installed with the software packages associated with the device.
lsslot -c phb
This displays output similar
to the following: PHB Name Description Device(s) Connected
PHB 1 Logical PCI Host Bridge pci0
pci2 scsi1
PHB 2 Logical PCI Host Bridge pci1
pci3
pci4 scsi2
lsslot -c phb
The output
will look similar to the following: PHB Name Description Device(s) Connected
PHB 4 Logical PCI Host Bridge
PHB 5 Logical PCI Host Bridge
