but In /dev/dsk/ the device files are present.
lssf output the device files is as bellow

sdisk card instance 161 SCSI target 4 SCSI Lun 7 section 0 at address ??? /dev/dsk/c161t4d7

I tried by removing the devices files manually,insf,insf -e,insf -e H 2/0/9.The xp lun security, WWN are ok.

Hi,

For first issue.

After allocating the LDEVs, u have run ioscan -fnC disk correct?. After that step did u run insf to install the disks, if yes, was it showing that the system is installing the device files.

run #xpinfo -i |egrep 'ldev1|ldev2' and check the o/p. Is it displaying the Luns.
If do pvcreate to those luns inorder to allocate it in a VG

Abt the second issue, can u clarify the query, i am not able to get u..

Regards,
Sunil

Shalom Sunil,

insf -e
insf -C disk

rmsf removes devices.

Please first make sure the World Wide Name (WWN) on the two HBA cards has been assigned to the luns in question.

Then understand that for full control you may need to reboot your system. You probably will as a matter of fact.
