Urgent: About VA7100 Configuration
Currently my customer just upgrade their VA7100, add in 7x73GB into existing 8x36.4GB. Their created 2 LUNs from the VA7100. I have copy down the ioscan -FunC disks outputs
and it shows
c1t2d0(root disk), c3t2d0(cdrom),
c5t0d0,
c5t0d1,
c5t0d2,
c5t0d3,
c0t5d4,
c0t5d5,
c5t0d6,
c5t0d7,
c5t1d0,
c5t1d1,
c7t0d0,
c7t0d1,
c7t0d2,
c7t0d3,
c7t0d4,
c7t0d5,
c7t0d6,
c7t0d7,
c7t1d0,
c7t1d1.
They have disable the secure manager and it shows double entry of LUNs. I guess the lun and physcial hard disks mix together.
2я╝Йif the 2 new LUNs is created, does it shows 4 new entries?
3) if yes, it is correct to just use 2 new LUN create the 2 file systems on just 2 of the 4 entries?
4) Following the steps to create 2 file systems after LUN create by commandview.
#ioscan -funC disk (scan Harddisk)
#pvcreate -f /dev/rdsk/cxtxdx (cxtxdx refer the LUN or physcial hardisk)
#mkdir /dev/vg03
#cd /dev/vg03
#mknod /dev/vg03/group c 64 0x030000
#vgcreate /dev/vg03 /dev/dsk/cxtxdx /dev/rdsk/cytxdx
#lvcreate -L 10000 /dev/vg03/lvol1
#lvcreate -L 35000 /dev/vg03/lvol2
#newfs -F vxfs /dev/vg03/rlvol1
#newfs -F vxfs /dev/vg03/rlvol2
After mount the file systems accordingly.
Best regards
Leon

Re: Urgent: About VA7100 Configuration
If VA7100 is connected to two HBA on host then you will find dual path for each LUNs you create and can be eliminated if secure path (SP) is installed. If you don't have the SP then choose the right path and create the LUN. Rest the steps to create filesystem is ok except
vgcreate /dev/vg03 /dev/dsk/cxtxdx /dev/dsk/cytxdx.

Re: Urgent: About VA7100 Configuration
When creating VG specify both PV names, or you do a VGextend to configure the alternate PV path.

Re: Urgent: About VA7100 Configuration
If HP-UX is connected to HP classic storage(VA) then secure path is not needed as any path failovers would be handled by LVM providing primary and alternate paths are configured.

Re: Urgent: About VA7100 Configuration
Since the output was there. Is following the command correct and special for the pvecreate and vgcreate?
#ioscan -funC disk (scan Harddisk)
#pvcreate -f /dev/rdsk/c5t0d0
#mkdir /dev/vg03
#cd /dev/vg03
#mknod /dev/vg03/group c 64 0x030000
#vgcreate /dev/vg03 /dev/dsk/c5t0d0 /dev/dsk/c7t0d0
#lvcreate -L 10000 /dev/vg03/lvol1
#lvcreate -L 35000 /dev/vg03/lvol2
#newfs -F vxfs /dev/vg03/rlvol1
#newfs -F vxfs /dev/vg03/rlvol2
After mount the file systems accordingly.
Hope can clearify that.
Best regards
Leon
