Where are my Disks in the Cluster ??????

[kumar.s]

Hello Everyone ,

We have a Service Gaurded node in our enviorement , Recently there was a LAN card replacement for the server , And after that i was not able to see some of the disk devices in the server

Below is the details all C31 devices are not sensing , I find few other alternate disk's are available /sensed at the server

Currently the package is running on the secondary node ,

# strings /etc/lvmtab
/dev/vg00
/dev/dsk/c4t0d0
/dev/dsk/c10t0d0
/dev/dsk/c4t1d0

# diskinfo /dev/rdsk/c31t1d7
diskinfo: can't open /dev/rdsk/c31t1d7: No such device or address

I have attached the ioscan out put , Wether if i failback the package will it be sucessfull or will it give errors , I have attached the ioscan & cmviewcl command out put herewith , Note the cluster uses the VG /dev/vg_edazcos2_99 .
