MD3000i multiple issues
I have a MD3000i that is reporting Impending Physical Disk Failure on 2 disk and also reporting Virtual Disk Not On Preferred Path.
Is it safe to first replace the two failing disk before attempting to fix the virtual disk not on preferred path?

Hello pdbarnes,
What you want to do is to replace the 2 disk first 1 at a time & let the rebuild finish before replacing the second disk. Once both disk are replace then follow the steps below to fix the virtual disk not on preferred path issue.
Virtual Disk Not On Preferred Path
The alert on the system is due to a virtual disk not being on the preferred path. When virtual disks are created, they are assigned to one of the two controllers as a preferred communication path. If that path is not available – due to a network issue, controller reset, etc. – the array will communicate via the alternate controller. In some cases the communication does not shift back to the primary path when it becomes available again. To correct this you just need to manually redistribute the virtual disks back to their preferred paths.
To redistribute virtual disks:
1. Open Modular Disk Storage Manager (MDSM)
2. Click on the Support tab
3. Select Manage Raid Controller Modules
4. Click on Redistribute Virtual Disks
• You will get an alert telling you that this will disrupt communications if you do not have the multipath drivers installed. You can ignore this message and proceed. If you still have access to the virtual disk that is not on preferred path, you have multipath drivers installed.
Please let us know if you have any other questions.
