On HP 3PAR Storage, disks are grouped inside magazines. So when it comes to replacing a failed disk, magazine that holds the disk has to be brought offline using a servicemag start command.
First, identify if there is a failed disk on the system:
cli% showpd -failed -degraded
-Size(MB)-- ----Ports----
Id CagePos Type RPM State Total Free A B Cap(GB)
125 3:1:1 FC 15 failed 278528 0 0:6:4 1:6:4* 300
-------------------------------------------------------------
1 total 278528 0
There is one failed 300GB FC disk with id 125.
Second, check if there is an ongoing servicemag operation:
cli% servicemag status
No servicemag operations logged.So we can start servicemag operation:
cli% servicemag start -pdid 125
Are you sure you want to run servicemag?select q=quit y=yes n=no: y
servicemag start -pdid 125
... servicing disks in mag: 3 1
... normal disks: WWN [XXXXXXXXXXXX] Id [126] diskpos [2]
.................... WWN [XXXXXXXXXXXX] Id [127] diskpos [3]
.................... WWN [XXXXXXXXXXXX] Id [206] diskpos [0]
... not normal disks: WWN [XXXXXXXXXXXX] Id [125] diskpos [1]
The servicemag start operation will continue in the background.
We should keep track of the status of the servicemag process and physical disk state (Note that magazine position is 3 1, we later use it after we brought it online):

servicemag start -pdid 125 -- Succeeded
After the magazine brought offline successfully, we can insert a new one by removing the failed disk physically. We ensure new disk plugged into the right place so we can bring the magazine online:
cli% servicemag resume 3 1
Are you sure you want to run servicemag?select q=quit y=yes n=no: y
servicemag resume 3 1

The servicemag resume operation will continue in the background.
It will take a couple of hours to recover:
