HP 3PAR RedHat and Oracle Linux Implementation Guide

15 Using Oracle Linux
HP supports Oracle Linux with both the RHEL-compatible kernel and with the UEK.
Oracle Linux with RHEL-Compatible Kernel
When using Oracle Linux with the RHEL-compatible kernel, follow the procedures in this guide for
the corresponding version of RHEL.
Using Oracle Linux with UEK
Oracle Linux UEK is an optimized package for Oracle software and hardware. The Oracle Linux
UEK is built upon the RHEL 6 kernel and is optimized specifically for Oracle software.
When using Oracle Linux UEK, follow the usage guide as outlined for the corresponding version
of RHEL Linux.
NOTE: At the time this guide was released, there was an issue with software iSCSI such that, if
iSCSI sessions were opened to exported LUNs from the array, the Oracle Linux host would hang
when a system reboot was attempted. A workaround for this issue is to log out of all iSCSI sessions
before rebooting the host. Use this command to log out of open iSCSI sessions:
# iscsiadm -m node --logout
There are no special considerations for the HP 3PAR StoreServ Storage when using Oracle Linux
V6.x UEK besides the standard setup procedures described in this implementation guide for RHEL
6.
Oracle Linux Creating Partitions
When creating Linux-type partitions on exported LUNs using either fdisk or parted, make sure
the correct partitions are listed as partition numbers p1 or other number. For example, here is an
exported LUN displayed using multipath -ll:
360002ac00000000000000265000185db dm-3 3PARdata,VV
size=15G features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=1 status=active
|- 0:0:0:32 sdd 8:48 active ready running
|- 1:0:0:32 sdh 8:112 active ready running
The following example uses parted to create the partition on the exported LUN:
parted /dev/skl
GNU Parted 2.1
