Removing an HBA

From a PowerPath

Configuration

PowerPath Administration on Solaris

To use DR to remove an HBA from a Solaris host in a PowerPath configuration, follow these steps:

1.Correlate the c#t#d#s# device special files of the HBA being removed with the PowerPath adapter number for that HBA. The PowerPath adapter number is used in the

powermt remove adapter command later in this procedure. On 10000 class systems:

•Start the dr shell. Enter: dr

The prompt changes to dr>.

•From within the dr shell, list the devices and corresponding c#t#d#s# device special files on the I/O board being removed. For example, for I/O board 1, enter:

drshow 1

The command returns output like the following:

I/O Bus Controllers and Devices for Board 1

----------- I/O Bus 1 : Slot 0 : esp0 ----------

device	opens	name	usage
------	-----	----	-----
sd838	4	/dev/dsk/c2t0d1s2	/test
...

drshow displays all device special files that point to HBAs on the I/O board. In the example above, board 1 Slot 0 has a single device (HBA) attached named c2t0d1s2.

•Press CTRL-Dto exit the dr shell.

•Associate the device special file (identified above with drshow) with a PowerPath adapter number. Enter:

powermt display dev=all
