HP 2000 Modular Smart Array Controller Firmware J202P01, J212P01, and J302P01 Release Notes (537811-008, December 2012)

NOTE: For multipath/dual HBA configurations connected to the same array, run the same
command for both HBAs. For example:
nl
echo “- - –” > /sys/class/scsi_host/host1/scan
echo “- - –” > /sys/class/scsi_host/host2/scan
For HPDM Multipath configuration, after running the scan command, run the following commands
to update the multipath maps in the kernel:
/etc/init.d/multipathd restart
/sbin/multipath —v3
• There is an issue with DMS where I/O can time out.
◦ The following conditions need to be true in order for this to occur:
– DMS is enabled.
– Snap Pool (aka Backing Store) and Master Volume are on the same vdisk.
– Host IOs are running. Based on what is observed during re-creating or failing to re-create,
it may only be brought out with heavy host IOs. Since there are not enough runs to make
it statistically significant, treat heavy IOs as an observation.
– There is a failover operation (as in a controller failure).
• Follow these steps if, on controller shutdowns or code updates, the surviving controller crashes:
1. Unplug all host interfaces from both controllers.
2. Reboot the crashed controller and perform the firmware update procedure again if applicable.
3. Once the code has been updated, or both controllers are now operational, plug the host
cables back in.
4. Bring the storage array back online to the host(s).
