I have create 7 vdisks at EVA and also presented the LUNS from the host and detected by ioscan command whereas for my 8th vdisk i have created with 500gb at EVA and presented the LUNS also but it is not detecting by ioscan command. I executed this command frequently and waited for 20min even also that h/w is not detected.

Re: vdisk h/w path is not detected
The other vdisks are of size 200gb, 150gb, 60gb like that. I have created these vdisks under FATA disk group.
For all these vdisks i have detected the LUNS whereas only for 500gb disk.
Justnow, i tried to delete this 500gb and created with 200gb and presented the LUNS to the host at EVA level and i checked for these LUNS at O/S level by ioscan even though also the LUNS are not detected.

Re: vdisk h/w path is not detected
Hi Dear,
Please check at your storage end, that the LUN presented properly to the host or not,
Your remaining 7 LUNS getting means hope there is no problem with your SAN zoning.
In sever before ioscan just execute
#insf -e
#insf -eC disk
then check ioscan, Hope the disk will detect.
thanks,

Re: vdisk h/w path is not detected
After presenting the LUN please run the ioscan command and the verify whether the new lun is showing or not. If not please run the insf -C disk command ,in the o/p you can see the new device file.

Prasanth Thomas
