How to Unconfigure IB Devices Connected to an HCA

An actual DR of an HCA is beyond the scope of the IB cfgadm plugin. Although DR of an HCA can be achieved by using the plugin of the underlying bus. For example, a PCI based HCA can use the cfgadm_pci command. For more information, see cfgadm_pci(1M).

However, the IB cfgadm plugin assists in the HCA DR by listing its kernel IB clients as illustrated in steps below.

1. Become superuser.

2. List the kernel IB clients of the HCA.

   For example:

   # cfgadm -x list_clients hca:173000007F50 Ap_Id IB Client Alternate HCA ib::1730000007F51D0 ibgen no ib::1730000007F51D1 ibgen no ib::1730000007F51,8001,ipib ibd no ib::ibgen,0 ibgen no - ibdm no - ibmf no - nfs/ib no

3. Unconfigure kernel IB clients, such as Port, VPPA, HCA_SVC, or IOC devices, that do not have alternate HCAs present.

   For example:

   # cfgadm -x unconfig_clients hca:1730000008070 Unconfigure Clients of HCA /devices/ib:1730000008070 This operation will unconfigure IB clients of this HCA Continue (yes/no)? y

4. Verify that the kernel IB clients of the HCA are unconfigured.

   # cfgadm -x list_clients hca:173000007F50 Ap_Id IB Client Alternate HCA - ibdm no - ibmf no - nfs/ib no #
