Create New FS on HP-UX 11.0

L1000, 11.0 OS

AutoRAID Array Model 12H w/ 12 18.2 GB disks

Online JFS installed



I have listed other information below.



I need to create a new filesystem of about 30 GB that can handle large files. I am going to mount this filesystem to another Unix server and dump a database.



I thought I could just go into Sam and create a new volume group, but when I get to the select disks part I am only given the option of the unused internal drive DMVS09D and the unused 2 GB LUN.



Viewing array status all 12 disks are included, with 121 GB unallocated.



My question is, how do I get to all of my other disks? Do I need to go through the arraymgr?



Thank you for your help.



Robb

Re: Create New FS on HP-UX 11.0

Robb,

It sounds like your AutoRAID LUNs have already been included into a Volume Group. A vgdisplay -v would show this. It would also show whether you have excess space in your Volume Group(s).

Here is the vgdisplay -v.

Re: Create New FS on HP-UX 11.0

Use SAM to create new LUNs first. You can create 2 LUN of 20GB each.

(SAM... Disk and Filesystem.. select AUTORAID.. Select Bind LUN).

Once the LUNs are created you can use SAM / command line to create VG -> LV-> FS

Robb,

According to that, I don't see one disk being used: /dev/dsk/c5t1d0 and it's alternate path /dev/dsk/c6t1d0. Perhaps these need to be included into a new lun?

Re: Create New FS on HP-UX 11.0

arraycfg -L LUN -a capacity

LUN - must be an unused value between 0 and 7
Capacity - must be less than or equal to the currently available unallocated capacity

with that you create a new LUN.

check unused LUN-ID with arraydsp -l

you get the array-id with arraydsp -i

you can check if you have enough unallocated space in your array with arraydsp -i


So I think to get a new LUN with 30GB you have to do this.

# arraydsp -i (to get array-id)
# arraydsp -l (to get free LUN-Number)

# arraycfg -L -a

# ioscan
# ioscan -fnCdisk
# insf -f (create device file for new LUN)

Now use SAM or CL to create your new vg that has enough space for your db backup.

Hope it helps !!

One typo:

to check unallocated space in array:
# arradsp -a |more

!!!!Notice!!!!

Unallocated disk
array capacity
Performance.

Unallocated capacity is used as additional RAID 0/1
space. The amount of RAID 0/1 space required to maintain optimal
performance is determined by the write working set parameter.
