Hi all ,
I have a problem with our new server setup in that from our proliant server running a Smart Array 6400 controller I cannot see the attached MSL2024 Library under RHEL 4. However the internal Ultium 960 drive is visable.
I've read that switching on LUN support is a remedy for this problem. However Does the Smart Array 6400 support this option ? If so does anyone know how i can turn it on ?

Re: MSL2024 can't be seen from SA6400 under RHEL 4
If I remember right it is not supported to connect external devices when internal HDD are in use ( connected to SA6400 ).

Re: MSL2024 can't be seen from SA6400 under RHEL 4
The Server utilises an internal SA 6i controller for the internal HDD.
The 6400 is connected to the MSL2024 on 1 of the 2 external ports and terminated. the 2nd of the 6400 ports is connected to a HP StorageWorks Modular Smart Array - SATA.
I pray i dont need a new controller solely for the MSL2024 !

Daren:
The issue in this case is LUN support. Because the SA6400 card is running in RAID (Smart Array) mode due to the MSA being attached, LUN is disabled. You are going to have to put the MSL on it's own card.
Running under RHEL 4 you will also need to configure multiple LUN support.
1)In /etc/modprobe.conf add the line:
options scsi_mod max_luns=xxx
(replace xxx with the number of luns to support)
2)Build the initial ramdisk to implement the change
mkinitrd -f /boot/newimage-2.6.xx 2.6.xx
(replace xx with the exact version of your kernel)
3)Reboot the system, and the LUNs should appear.
This should take care of the issue for you.
