VA7100 Configuration

Hi Experts,

Exist Infrastucture have 3 x L2000 servers connect(reduant connection) with 2 Brocade switchs, the 2 switchs connect with 1 x VA7100 (currently 8 Harddisks). My Questions will be

1.If plug with another new 7 new harddisk in VA7100. Do I need shutdown the server and VA7100?

2. If I want create new volume for VA and mount the new volumes on the L2000. Is it smiliar like
#iocan -funC disk (scan Harddisk)
#pvcreate -f /dev/rdsk/cxtxdx
#mkdir vg03
#cd vg03
#mknod /dev/vg03 group c 64 0x010000
#lvcreate -L /dev/vg03
#newfs -F vxfs/dev/vg03
mount the volume accordly
edit /etc/fstab ?

Kind correct me if i am wrong.

Leon,

You don't have to shutdown the VA7100. The autoinclude option must be on for the disks.
Be are that rebuilding the VA can take some time and performance.

The ux command are OK after the creation of an extra LUN

Hi Leon,

1)Yes you don't have to shutdown the VA, but be very careful when you had disk into the array.
It's preferable to add one disk and wait for the formating process to end, and then add another disk...(formating could be 30mn long by disk).

2) there is some error into your sequence.
a possible sequence could be as follow

#ioscan -funC disk (scan Harddisk)
#pvcreate -f /dev/rdsk/cxtxdx
#mkdir /dev/vg03
#cd /dev/vg03
#mknod /dev/vg03/group c 64 0x030000
#vgcreate /dev/vg03 /dev/dsk/cxtxdx /dev/rdsk/cytxdx (usually 2 controller on VA7100)
#lvcreate -L /dev/vg03/lvol1
#newfs -F vxfs /dev/vg03/rlvol1

BR,

Leon,

You have to create a new LUN and assign it to a particular server using secure manager. Then you will be able to locate them in ioscan output fot that server and follow your procedure.

Cheers
