Bug ID 20774477: If you use SES-enabled storage devices, you might see a device busy error when you attempt to remove a PCIe bus that hosts these devices. To determine whether you are using this type of storage device, search for the ses or enclosure string in the ldm list-io -l output for the PCIe bus.
Workaround: Perform one of the following workarounds to remove the PCIe bus:
Dynamically remove the PCIe bus.
Disable the FMD service.
primary# svcadm disable -st svc:/system/fmd
Remove the PCIe bus.
primary# ldm remove-io bus
Re-enable the FMD service.
primary# svcadm enable svc:/system/fmd
Statically remove the PCIe bus.
Place the root domain that has the PCIe bus in a delayed reconfiguration.
primary# ldm start-reconf root-domain
Remove the PCIe bus.
primary# ldm remove-io bus
Perform a reboot from the root domain console.
root-domain# reboot
