INSTALLING THE PP_INQ UTILITY
ENVIRONMENT
***********
The pp_inq utility is supported in the following environments:
- Operating systems: RHEL 4.2-8, RHEL 5.0-4, SLES 9 SP4, SLES 10 SP2 and SP3,
and SLES 11
- Platforms: All supported hardware architectures (i386,x86_64,ia64 and ppc64)
- PowerPath versions: PowerPath Linux 5.3 SP1, PowerPath Linux 5.3 SP1 Patch 01
and PowerPath Linux 5.3 SP2
UTILITY DESCRIPTION
*******************
Version 7.3-956 (Rev 1.34) of the pp_inq utility fixes a problem in which the
/etc/init.d/PowerPath start command takes a long time to complete when
PowerPath manages EMC Invista or VPLEX Virtual Volumes. The more Virtual Volumes
PowerPath manages, the longer the command takes to complete.
This utility addresses known issue 330367.
INSTALLING THE PP_INQ UTILITY
*****************************
To install the updated pp_inq file:
1. Install PowerPath.
2. Make a backup copy of pp_inq, which resides in /sbin/pp_inq.
3. Copy the udpated pp_inq.<arch> file contained in the package
on Powerlink to /sbin/pp_inq. Select the appropriate file for
your architecture, as follows:
i386(32-bit) pp_inq.386
x86_64 pp_inq.x8664
ia64 pp_inq.ia64
ppc64 pp_inq.ppc64
For example, to copy the updated file on a x86_64 system,
use this command:
cp pp_inq.x86_64 /sbin/pp_inq
5. Change permission for /sbin/pp_inq to 755 using the
chmod command.
For example, enter:
chmod 755 /sbin/pp_inq
6. The next time PowerPath is started or the host is rebooted,
the updated pp_inq file will be used.
If you upgrade or reinstall PowerPath, you must redo these steps
to update pp_inq again.
