Linux connnectivity problem
Dear All,
Does anyone experience the following error about linux connnectivity?
1. disk I/O is OK. I can use the emc disk to read/write, mount/umount.
2. Use "mount /emcdisk" to mount the disk sucessfully and I have added the entry on "fstab" file
3. get a error like this
fsck.ext3: No such file or directory while trying to open /dev/sdb1 [FAILED]
*** An error occured during the file system check.
I can mount the disk normally when I keyed the root's password into maintance mode. It seems the emc disk not ready during booting system.
The host register info as following:
1. Clariion Open
2. Failover mode 0
Thanks for any reply.

Thanks for your reply first.
I have installed EMCpower.LINUX.5.0.0.157.tar.gz, but no powerdisk it can create.
There is only one path direct attached to CX3-10c due to cost issue.
finally I remove the powerpath and face mount error via fstab.

If would also be helpful to know if you do have a single HBA are you zoned to multiple Clariion ports or is it a 1-to-1 mapping?

I set failover mode back to 0 when I remove the PP.
So it's not the issue in my case.
Is it possible the disk not ready (/dev/sdb1) during booting system?
I saw some messages error about powerpath can't find something druing booting.
Thanks,
Dennis

mke2fs -j -L rac_ora1 /dev/sda1
so when they mount the file system they use labels instead of devices names, that way if device changes its name ..it can still be mounted since the label remains the same. Here is my /etc/fstab
LABEL=rac_ora1 /rac/rac_ora1 ext3 defauls 1 1

I installed PowerPath in order to get fixed disk naming.
It prevents disk changes from system reboot.
