Encrypted Volume and File System v2.2 Administrator Guide (777846-001, April 2014)
Solution
This error occurs when the mapping is not initialized correctly. Make sure that there is no problem
with the volumes and use the evfsadm map –a command to restore the mapping.
Error on mounting file system
Make sure that you run fsck as follows after you reset the dirty bit of an EMD, or if the EMD is
corrupted and you recover it from the EMD backup file by doing evfsvol restore
evfs_volume_path:
fsck [-F file_sys_type] raw_evfs_volume_path
Without running fsck, you may not be able to mount the file system on the EVS volume successfully.
evfsvol cannot create an EVFS volume
Symptom
The evfsvol create command fails and evfsvol displays a message similar to the following:
evfsvol: create error: unsupported digest "sha1"
Description
The evfsvol utility cannot create an EVFS volume because SHA1 is no more supported for
calculating EMD digest.
Solution
Check the value of emd_digest in the EVFS configuration file /etc/evfs/evfs.conf.
If the value is SHA1, replace this with SHA2.
Reporting problems
If you are unable to resolve a problem with EVFS, complete the following steps:
1. Read the EVFS product release notes to see if the problem is a known problem. If it is, follow
the documented solution.
2. Determine if you have a valid warranty or support contract for your HP-UX system. Your
operations manager can supply you with the necessary information.
3. Go to the HP Support Center website at the following URL:
http://www.hp.com/go/hpsc
Search the technical knowledge databases to determine if the problem you are experiencing
has already been reported. The type of documentation and resources you have access to
depend on your level of entitlement.
4. If this is a new problem or if you need additional help, log your problem with the HP Support
Center, either on line through the support case manager at http://www.hp.com/go/hpsc, or
by calling HP Support.
If your warranty has expired or if you do not have a valid support contract for your product,
you can still obtain support services for a fee, based on the amount of time and materials
required to solve your problem.
Collecting data
Collect and submit the following data when reporting a problem:
• A description of your environment, including the HP-UX and EVFS version numbers.
