Detect LUNs on Hewlett Packard Blades

1. HP tools for Blade Systems

# hp_rescan -a;

2. Using PowerPath driver

# powermt config;
# powermt save;

3. Using as $LUNID the serial number provided by Storage team.

# powermt display dev=all|grep -E "Pseudo|Logical"|sed -e :a | grep -2 $LUNID

4. If you're using VXVM:

# vxdctl enable; vxdisk scandisks;

............................................................................
Note: Probably you don't have the HP tools propertly configured, in that case you could run:

echo 1 > /sys/class/fc_host/host0/issue_lip
echo "- - -" > /sys/class/scsi_host/host0/scan
echo 1 > /sys/class/fc_host/host1/issue_lip
echo "- - -" > /sys/class/scsi_host/host1/scan

# powermt config;
# powermt save;
# vxdctl enable;
# vxdisk scandisks;
