Hi all, OEL 5.8 64bit 2.6.32-300.10.1.el5uek GI 11.2.0.3.3 (PSU July 2012) According to MOS Note 1408670.1 ACFS support for UEK 2.6.32-300 will be in 11.2.0.3.2 GI PSU (we have 11.2.0.3.3 PSU). This is part of the PSU installation output: [...] patch /xxxx/13919095 apply successful for home xxxx patch /xxxx/13923374 apply successful for home xxxx ACFS-9300: ADVM/ACFS distribution files found. ACFS-9307: Installing requested ADVM/ACFS software. ACFS-9308: Loading installed ADVM/ACFS drivers. ACFS-9321: Creating udev for ADVM/ACFS.

ACFS-9309: ADVM/ACFS installation correctness verified. CRS-4123: Oracle High Availability Services has been started. I didn't check the ACFS status right after the installation, but after rebooting the nodes I noticed that the ACFS drivers are not automatically loaded: [grid@xxxx]$ acfsdriverstate -orahome /xxxx installed ACFS-9203: true [grid@xxxx]$ acfsdriverstate -orahome /xxxx loaded ACFS-9204: false [grid@xxxx]$ acfsdriverstate -orahome /xxxx version ACFS-9325: Driver OS kernel version = 2.6.32-300.0.4.el5uek(x86_64). ACFS-9326: Driver Oracle version = 120603. [grid@xxxx]$ acfsdriverstate -orahome /xxxx supported ACFS-9200: Supported Any ideas? Found the following Note on MOS, but this is RAC environment: ACFS/ADVM is NOT started automatically after node reboot or after CRS is restarted in non-RAC environment [ID 886407.1] (I didn't try acfsload start –s yet and I'll open an SR tomorrow) Thanks Dimitre -- //www.freelists.org/webpage/oracle-l
