Adding raw logical volume in package control file

[Sudhir Junonikar]

Hi!!!

I am new to HP UX, i am trying to insert raw logical volume in Dataware house package control file & changes are as per below

VG[0]=vgrbldwh

LV[0]=/dev/vgrbldwh/rlarchrbldwh1; FS[0]=/archrbldwh1; FS_MOUNT_OPT[0]="-o rw,
largefiles"; FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""; FS_TYPE[0]="vxfs"
LV[1]=/dev/vgrbldwh/rlarchrbldwh2; FS[1]=/archrbldwh2; FS_MOUNT_OPT[1]="-o rw,
largefiles"; FS_UMOUNT_OPT[1]=""; FS_FSCK_OPT[1]=""; FS_TYPE[1]="vxfs"

but package is not getting started it gives the following error in package log file

########### Node "dbnode": Starting package at Sat Nov 15 23:55:15 IST 2008 ###########
Nov 15 23:55:15 - Node "dbnode": Activating volume group vgrbldwh with exclusive option.

########### Node "dbnode": Package start failed at Sat Nov 15 23:55:16 IST 2008 ###########

I am not understanding that i have entered logical volume as /dev/vgrbldwh/rlarchrbldwh1 & it taking it as /dev/vgrbldwh/rrlarchrbldwh1 while file system check.

any answers,links etc are appreciated.

Thanks in advance

You do not have to add the raw LV to a package control file. As long as the VG is there it activates the VG and the raw LV can be accessed by the application. The LV and FS pairs of entries are to mount filesystems only.

Hi Sudhir,

raw device files contains no File system that why its called raw device file you just need do only lvcreate on the required VG,

please those entries on the pkg.cntl.file

nature of raw device files
===========================
performance benefit from using raw devices, since a write
to a raw device bypasses the UNIX buffer cache

Thanks,
Johnson

yep, no need to add the raw LV to a package control file. you just have to add the VG

Hi Sudhir kolahapur cmc,

How many nodes are in ur setup .you have to do the export/import the vg on its adoptive (failover node) nodes means HA/DR.
