Veritas clean meanings of fsdb command ?

Hello everyone.

My customer have solaris 9.
The system installed products to SF4.1MP2RP4 , sun-cluster 3.1 and MPxI/O.

I saw the dmpevent.log.
=======================================================================================================
I/O analysis done on Path c1t6006016093E0100083D5448ADF5DDD11d0s2 belonging to Dmpnode EMC_CLARiiON0_14
I/O error occured on Path c1t6006016093E0100083D5448ADF5DDD11d0s2 belonging to Dmpnode EMC_CLARiiON0_14

   .
   .
   .
=======================================================================================================
however, I not saw other error messages. such as, system-log and dmesg.
EMC_CLARiiON0_14 is a /dev/vx/rdsk/apdata-dg/vol01.
I had to check file-system. Here's the info:
#echo '8192B.p S' | fsdb -F vxfs /dev/vx/rdsk/apdata-dg/vol01 | grep flags
fsdb: bad super-block or metadata - setting block size to 1024
                                - setting ino per extent to 32
flags 0 mod 0 clean 0
==============================================================
What's "clean 0" ?
Do I need the fsck command ?
Other file-systems are "clean 3c".

Hello, for flags in


Hello,

for flags in filesystem:

5a indicates clean
3c indicates dirty   (This is common if FS is mounted, if you clean unmount FS, it should be 5a)
69 indicates dusty, has pending extended operations

0 probably is indicating unknown status since it can't read superblock....  you can try for fsck however I believe it will report same saying "bad superblock"

Do you have a tape backup of FS ?
