How to view the allocated lun in linux

[senthil_kumar_1]

Hi

I am using Suse 9 Enterprise linux. qlogic card is connected.

Now a LUN has been assigned to the this server.

I used following command to view the new lun.
But i am not able to see the new LUN.

Ex:
1) fdisk -l
2) lsscsi

What is the command is used to view the newly allocated LUN with out restarting the linux server.

or can we see the newly allocated LUN defenitely after rebooting the linux server?

Hello Senthil,

you should run hp_rescan to first see the luns.

then can use fdisk or parted command to creaet new partition as per requirement, thanks,

Hi Friends,

Thanks a lot,

Now i am able to see the availabel LUN using the command "hp_rescan".

is this command "hp_rescan" installed by default with suse and redhat?

if not, how to install this in suse and redhat linux.?

[Ivan Ferreira]

No, the command is part of the fibreutils package provided by HP with the Proliant Support Pack. You can download the package from the HP site.

Hi Ivan Ferreira,

Before i did not worked in hp servers.

do we need to install "Proliant support pack" after installing the linux?

is this "proliant support pack" is used to setup HBA card?

we are using qlogic card.

can this "proliant support pack" be used to setup any HBA card other than qlogic?

is qlogic hp product?

>> do we need to install "Proliant support pack" after installing the linux?

It's recommended

>>> is this "proliant support pack" is used to setup HBA card?

Yes, it contains drivers/modules for HBA's

>>> we are using qlogic card.

Normally, the HP provided HBA's are qlogic cards with different part numers

>>> can this "proliant support pack" be used to setup any HBA card other than qlogic?

Not sure

>>> is qlogic hp product?

HP provides QLOGIC HBAs with different part numbers.

Hi Ivan Ferreira,

Pls explain me about different part numbers.

MUST - Install the latest PSP -MUST.

Your commands then of interest for SAN disks are:

hp_rescan - covered above
lssd [ -l ] (or is it -v ?)
lssg [ -l ] (same.. -v)
maybe you should use #yast2 for LSM/ext3 config.

other:
lsscsi - creates dev files (rescan does this too)
blkid - shows disk UUIDs
