Insert a second Virtualized M2 NEM into an empty chassis slot.

The NEM is automatically registered with the CMM. The second NEM will obtain zoning configurations from the first NEM. Any future saved configurations remain unchanged if the NEM is removed and reinserted the same slot. The external port configuration is not copied over from the existing NEM to the new NEM, but the NEM external SAS ports are not currently supported.

• None. When using a SAS-2 REM configured for RAID, dual path support to storage will automatically be enabled.

• When using a SAS-2 REM not configured for RAID, dual path support might need to be configured at the OS level. Check your OS documentation for information on enabling SAS multipath support.

Remove and insert the same Virtualized M2 NEM into the same chassis slot.

Since the NEM is already registered with the CMM, the NEM zoning configurations will remain unchanged.

The host REM might identify the storage module virtual drives as a foreign configuration (MegaRAID), or inactive (Fusion-MPT IR). A foreign or inactive configuration can be recovered using the REM management software. For MegaRAID, use the import feature described in the LSI MegaRAID SAS Software User's Guide. For Fusion-MPT IR, use the activate feature described in the LSI SAS2 Integrated RAID User's Guide.

Remove and insert a Virtualized M2 NEM into a different slot in the same chassis..

Upon insertion into the chassis, the SAS zoning configurations on the NEM expanders are deleted.

The NEM is automatically registered with the CMM. Any future saved configurations remain unchanged if the SAS-2 NEM is removed and reinserted in the same slot.

• Restore zoning configurations from a backup of CMM configurations. See Recovering Zoning Configurations

  —Or—

• Use the CMM zoning utility to re-assign storage module resources to SAS-2 server blades.

Replace a failed Virtualized M2 NEM.

• If there are two Virtualized M2 NEMs, upon insertion in the chassis, the replacement NEM is automatically registered with the CMM. The replacement NEM obtains configurations from the first NEM, except for external port configurations. Any future saved configurations remain unchanged if the NEM is removed and inserted in the same slot.

• If there was only one Virtualized M2 NEM, upon insertion into the chassis, the SAS zoning configurations of the replacement NEM expanders are deleted. The NEM is automatically registered with the CMM. Any future saved configurations remain unchanged if the NEM is removed and inserted into the same slot.

• If there were two Virtualized M2 NEM, no further action is needed..

• If there was only one Virtualized M2 NEM, restore zoning configurations from a backup of CMM configurations. See Recovering Zoning Configurations

  —Or—

• If there was only one Virtualized M2 NEM use the CMM zoning utility to re-assign storage module resources to SAS-2 server blades.

• If there was only one Virtualized M2 NEM, the host REM might identify the storage module virtual drives as a foreign configuration (MegaRAID), or inactive (Fusion-MPT IR). A foreign or inactive configuration can be recovered using the REM management software. For MegaRAID, use the import feature described in the LSI MegaRAID SAS Software User's Guide. For Fusion-MPT IR, use the activate feature described in the LSI SAS2 Integrated RAID User's Guide.

Connect a SAS-2 JBOD to the SAS-NEM external SAS ports.

Not currently supported.

Do not connect external SAS storage to the NEM external SAS ports.
