Just for reference purpose:
Recently I was testing some disaster recovery scenario of restoring Server A to Server B with identical hardware using Symantec Backup EXEC 2014 Simplified Disaster Recovery [SDR]CD. The hardware specs were as follows …
IBM Xseries 3650 M4, with RAID1
Dual Q.Logic Fiber Channel cards Mode: QLE2560 connected with two FC switches for multi path and failover
32 GB RAM,
IBM v3700 storewize SAN Storage
The restore went fine , system boot fine for the first time with everything intact, but when I rebooted it again , it failed to boot and shows only cursor blinking, As showed in the image below …
I tried to boot it several times but with no results. I then removed the FC cables from the server’s Qlogic FC cards, and this time windows booted fine.
I started the server without FC cables attached, then I removed the Windows MPIO features from ADD REMOVE FEATURES, and rebooted again with FC cables attached, and this time it works fine but showed duplicate SAN partitions. Then I applied IBM’s SSDM MPIO driver (MPIO_Win2008_x64_SDDDSM_64_2434-4_130816 for v3700 storewize) and everything went fine🙂
