Troubleshooting Questions and Answers Why did all the snapshots in my pool suddenly go offline? Currently, when a pool reaches maximum capacity, all snapshots contained within it go offline. For more information, see "Ensuring Pool Capacity for Your Snapshots" on page 67. Always carefully monitor the capacity of any pool that contains snapshots to avoid a lengthy recovery process or possible snapshot loss. To recover from a pool capacity failure, see "Recovering Snapshots After a Pool Capacity Failure" on page 148. How do I recover storage space from a mirror plex that's gone offline? If a mirror plex becomes unavailable (due to a power failure or a failed disk drive, for instance), you must first permanently disassociate it from the mirror manager (see page 74), then delete the underlying logical device to recover the storage space (see page 100). Why aren't email notifications being received properly? If the system designated to receive email notifications is not receiving them: • Ensure that the recipient's email address is correct. (See "Modifying a Recipient's Information or Removing a Recipient" on page 122 to modify the address.) • Ensure that your SMTP server address is correct. (See "Modifying Email Settings" on page 123 to modify the address.) Send a test email to ensure that the problem is solved. (See page 122.) Why am I getting an error message that says 'N-way mirroring not supported'? If you change the IP address of an iSCSI Storage Appliance used in a mirror, this message may appear when you try to create a mirror on that appliance. Use the CLI to update the IP address in the controller list for each mirror partner. If the iSCSI Storage Appliance is no longer used in a mirror, delete the IP address entry from the controller list. How can I stop Adaptec Storage Manager from generating 'Terminating connection' messages about my VMware systems? To stop receiving 'Terminating connection' messages from the VMware systems accessing storage on your iSCSI Storage Appliance, enable the VMware iSCSI initiators' "Uses permanent discovery session" option (in the initiators' Advanced settings). 140 Snap Server 700i Series User's Guide
