HPDM Multipath restrictions

HPDM Multipath has the following restrictions:

• HPDM Multipath does not provide an auto-failback feature for devices presented through iSCSI

Initiators. H P recommends running the following commands to recover the failed paths and make

them available for I/O failback (a quiesce of I/O is necessary; a reboot also may be required):

# /etc/init

.d/iscsi restart or # /etc/init.d/open-iscsi restart

# /sbin/multipath –v3

• No clustering support

• If De vice M

apper Multipath is conﬁgured on iSCSI devices (on hosts running SLES OS), the system

may hang du

ring reboot. To avoid this, HP highly recommends running the following command

before re

booting the system:

# /sbin/multipath –F
