Avoiding problem situations

The following sections describe problems tha t m ay arise and their solutions.

QLogic failove

r preference

If you are usin

g the built-in failover functionality of the QLogic driver, set the failover preference to

Path A Failove

r or Path B Failover in the M anagement Appliance. Failure to do so ca n cause I/O

errors when a f

ailover occurs.

Forcing a probe-luns command

If a Red Hat EL 3 U6 platform does not detect all LUNs, you can force a probe with the probe-luns

command at system boot. Enter the following command to install the p robe-luns startup code:

#cd /opt/hp/hp_fibreutils/pbl

#.pbl_inst.sh –i

NOTE:

Do not run probe-luns at system b oot if your server detects all LUNs.

To remove the probe-luns startup co de, enter the following comm and:

#cd /opt/hp/hp_fibreutils/pbl

#.pbl_inst.sh –u

Codeload usage

When a maximally conﬁgured system is running at full load, codeload functionality is not effective

because the system may time out before codeload is complete. HP recommends that you always perform

VCS upgrades at an off-peak time.
