[10ft]

Dear Gurus,

I've two proliant running Linux RH ES 4 up 4

Using HP EVA System Management Server, when we assign a lun to a server after a reboot the disc disappear to the system.

Whit hp_rescan -a and vgchange of volume group, disk (sda, sdb, sdc ecc ecc) appear again.

Is it possible see the disks after reboot?
My FC is a qlogic.

Thanks
Simone

If you have problems detecting listed devices during system boot. If you have trouble detecting these devices, run the /opt/hp/hp_fibreutils/probe-luns script during system boot.

Enter the following commands to install the probe-luns startup code:
# cd /opt/hp/hp_fibreutils/pbl
# ./pbl_inst.sh -i

Enter the following commands to remove the probe-luns startup code:
# cd /opt/hp/hp_fibreutils/pbl
# ./pbl_inst.sh -u

Thanks !!!

What is the difference between

/opt/hp/hp_fibreutils/probe-luns

and
./pbl_inst.sh -i

I have to put one of this script at startup
or i have to run pbl_inst.sh only one time to probe lun ?

pbl_inst.sh will install probe-luns into rc.sysinit

Just run pbl_inst.sh and it's done.
