When we use IBM medium- to low arrays, just like DS4000 series, install IBM SDDDSM (or RDAC) multipathing software at the same time. There will be blue screen phenomena when we reboot the system in the SFWHA5.x system.
1. The blue screen code is 0x0000007E.
2. Looking from the blue screen information, it’s lead by ds4dsm.sys driver.
Uninstall IBM SDDDSM (or RDAC) multipathing software, then install Veritas DMP DSM multipathing software.
Because we install IBM SDDDSM (or RDAC) multipathing software, we can see from Veritas Storage Foundation (tm) and High Availability Solutions 5.0 &5.1(SFW/SFW HA)’s Hardware Compatibility List （HCL）, SFWHA don’t bear IBM DS4000 series or lower, it just bear Veritas DMP DSM.
