Hi,
I have a quick question. I have an RP4410 Server running hp/ux 11.11 Operating system , and an external storage disk device MSA30.
I am adding new disks tomorrow to the MSA30 , and as they are plug in direct , does the Operating system see them instantly ? or do I have to run a command on the unix side to actually pick them up as 'physical disks'
Thanks a mill
Dave

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
Ioscan should pick them up right away.

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
Cheers Pete,
so literally just 'ioscan' without any switches or qualifiers ?

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
Cheers to you, too!
Full syntax should be "ioscan -fnCdisk", though you could certainly leave off "Cdisk" if you don't mind wading through all the extra output.

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
Before running the ioscan just take the output # ls -ltr /dev/rdsk/ | tail -10. So that after running the ioscan you can easily notice the new disk device file. If still you are not able to see the new disk then run # insf -eC disk command.

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
You will probably also need to tell the system to create the device files for the disks. You do this with the 'insf' command.
The procedure I usually follow:
ioscan -fnC disk ---> This makes sure that the new disks are accessible by the OS.
insf -C disk ---> Creates the device files for the disks
ioscan -fnC disk ---> This will show the device files that were just created for the new disks.

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
Hey;
I believe it was stated above, but just to be clear: you need two commands:
ioscan -fnC disk # rescans the bus
insf -eC disk # create the new device drivers.
Hope that helps.

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
It depends ...
Is the MSA30 connected to a plain SCSI controller or a smart array controller (e.g. sa6400)?
"ioscan -fn" will tell you.
Procedure depends on this!
Hope this helps!
Regards
Torsten.

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
OK , thats great , just have one more question here , If I add two new disks , and I want to make them 'raided' (i think is the phrase) , so if one goes bang , the other keeps the data intact , and we just need to replace it and it builds itself back into the two disk set , how do i configure this ?

Re: ADDING NEW DISK CAPACITY FROM O/S LEVEL QUERY
For this functionality you need a smartarray controller installed in the server. You can configure RAID1 or RAID5 on the disks. In case of a disk failure just replace the disk - done.
Otherwise you can mirror the disks with LVM, but you need to do adjustments after a disk replacement.
Please show your
# ioscan -fn
Hope this helps!
Regards
Torsten.
