Hotswapping disks in OpenSolaris
Adding new SATA-disks to OpenSolaris is easy and it’s done with cfgadm command line util if the disk is in a normal ACHI SATA controller. I have also an LSI SAS/SATA controller SAS3081E-R which uses its own utils.
Hotpluging disk into normal ACHI SATA controller.
First add the new disk to the system and power it on (a good sata backplane is a must) and then type cfgadm to list all disks in the system:
garo@sonas:~# cfgadm Ap_Id Type Receptacle Occupant Condition c3 scsi-bus connected configured unknown pcie20 unknown/hp connected configured ok sata4/0::dsk/c5t0d0 disk connected configured ok sata4/1 disk connected unconfigured unknown sata4/2 sata-port empty unconfigured ok
This shows that disk sata4/1 is a new disk which have been added but is not yet configured. Type
garo@sonas:~# cfgadm -c configure sata4/1
Now the disks are configured. Typing cfgadm again shows that they have been configured as disks c5t0d0 and c5t1d0. They’re now ready to use in zpools.
Hotswapping disks in LSI SAS/SATA controller
I have also an LSI Logic SAS3081E-R 8-port (i:2xSFF8087) SAS PCI-e x4 SATA controller which can be used with Solaris default drivers, but it should be used with its own drivers (i used the Solaris 10 x86 drivers). After the drivers are installed you can use the lsiutil command line tool.

Select a device: [1-1 or 0 to quit]
First select your controller (I have just one controller, so I’ll select 1). Then you can type 16 to Display attached devices, or 8 to scan for new devices. The driver will automaticly scan for new disks once a while (at least it seems so), so the disk might just pop up available to be used with zpool without you doing anything for it.
