The customer tried to upgrade UltraPath from 8.05.008 to 8.06.063 (V100R008C50SPC500), the system being suse11 x86-64 sp4.
However the process failed and the following error appeared: insmod: error inserting '/UltraPath/install/kernelModules/SLES11SP4_default_x86_64/nxupext_b.ko': -1 Resource temporarily unavailable.
Solution
1. After checking the compatibility, it was found that suse11 X86-sp4 does not support any UltraPath upgrade, it only supports installation.
2. Reinstall UlthaPath, then reboot the server.
3. Install UltraPath successfully and no error will appear.
