two questions with isp cfgMarkNonOptimalDriveGroupOnline,<SSID> command and other issue.

I have two questions may need your opinion,
1st is with the command of isp cfgMarkNonOptimalDriveGroupOnline,<SSID> in E-series hardware product with the drive offline issue in controller firmware of 6 .
In our internal reference, it is mentioned this command can only be applicable when only one disk is with Failed status, such as below,
I want to know if that is ture or not with the limitation of failed disk.
Ch Devnum Phydev State/Status Flags #Pcs Dg# T/S
0 000001 0837bc98 OPTIMAL/OFFLINE 00200000 0001 3 0/1
0 000007 0836e6e0 OPTIMAL/OFFLINE 00208000 0001 3 0/7
0 000006 0836ebc8 FAILED/WRT_FAIL 00200000 0001 3 0/6
0 000004 0836f0b0 OPTIMAL/OFFLINE 00200000 0001 3 0/4
0 000002 08377eb8 OPTIMAL/OFFLINE 00200000 0001 3 0/2
0 000005 083783a0 OPTIMAL/OFFLINE 00200000 0001 3 0/5
0 000003 08375f0c OPTIMAL/OFFLINE 04200000 0001 3 0/3
2nd question is with one function of SANTRICITY,
when drive wth Incompatitable status, we can using below function to clear the invalid dacstore info, so the disk
can be returned to optimal status.
dstStartStop (devnum,1,0) isp dsmWipe,devnum,1 Unseat the drive wait 30 seconds insert the drive
There is one function called Initialize in the SANTRICITY, I wonder if that option share the same function with upper command,
Just erase the dacstore info on the incomptitable disks and after that,
I can use recover script to recover the data on that disk.
Thank you for your help on the upper two questions.

There are situations (config issues, multi-drive failures, controller reboots, and so on.) that might cause the drives to go to an offline state.
If the volume group is offline due to any of these you can use cfgMarkNonOptimalDriveGroupOnline to get the volume online.
When you initialize a physical disk, all old volume group and volume information is erased and the physical disk is returned to an unassigned state. Returning a physical disk to an unassigned state adds unconfigured capacity to a storage array. You can use this capacity to create additional volume groups and volumes. CAUTION Potential data loss. When you initialize a physical disk all data on the physical disk is lost.
