为什么RHEL 6上没有ASMLIB

There are a few reasons why ASMLIB may not be present on a RHEL 6 system. One reason could be that the system was not originally installed with ASMLIB and was later upgraded to RHEL 6. Another reason could be that ASMLIB is not supported on the specific hardware platform or kernel version that is running on the system.

If ASMLIB is not installed on the system, it can be downloaded and installed from the Oracle Technology Network (OTN) website. Instructions for doing this can be found in the Oracle ASMLIB Installation Guide for Linux.

If ASMLIB is not supported on the system, there are a few workarounds that can be used. One is to use the Oracle Automatic Storage Management (ASM) feature instead of ASMLIB. This can be done by creating an ASM disk group and using the ASMlib utilities to configure ASM to use the disk group. Another workaround is to use the raw devices that are associated with the disks that will be used for ASMLIB. The raw devices can be configured manually or by using the asmlibconfig utility.
