6.3.3 HP StoreAll OS Release Notes (AW549-96082, January 2014)

Antivirus support
• If McAfee is used as a virus scan engine, when virus definitions are updated on the virus scan
engine, the updated definitions are not sent automatically to the StoreAll servers. To correct this
condition, request hotfix HF692368 from McAfee.
• For performance reasons, when an NDMP backup is in progress, Antivirus scans are not triggered
for the files being backed up. The StoreAll server excludes the process corresponding to NDMP
from scanning any files on a cluster with Antivirus enabled.
HP recommends that you disable Antivirus on the file system when a non-NDMP backup is in
progress. StoreAll cannot exclude a non-NDMP backup process from scanning files during a
backup. Disabling Antivirus prevents scans for files being backed up, which improves backup
performance.
• When WebDAV is enabled, the internal WebDAV files in the root of the file system are scanned.
To exclude all .lock/.pag files in the .DAV and .webdav directories from scanning, complete
these steps:
1. After the WebDAV share is created, unset the immutable bits on .webdav directory:
# chattr -i .webdav/
2. Run the following command to exclude all files in the .webdav directory:
# ibrix_avconfig -a -E -f FS1 -P /FS1/.webdav/ -x '*'
3. Reset the immutable bit on the .webdav directory:
# chattr +i .webdav/
4. Exclude all files in the .DAV directory for each HTTP/WebDAV share created:
# ibrix_avconfig -a -E -f FS1 -P /FS1/httpshare/.DAV/ -x '*'
Block snapshots
• Deleting files while running snapshot reclamation can cause errors to be logged. The impact is
negligible, unless you want to delete the entire snaptree, in which case snaptree deletion will fail.
To workaround this issue, run snapshot reclamation job again.
• Snapshot creation may fail while mounting the snapshot. The snapshot will be created successfully,
but it will not be mounted. Use the following command to mount the snapshot manually:
ibrix_mount -f <snapshotname> -m /<snapshotname>
• Quotas are disabled on block level snapshots (for example, MSA2000 snapshots) and the quota
information from the origin file system is not carried to the block level snap file system. Block level
snapshots are temporary file systems that are not writable. Users should not query quota information
against block level snap file systems.
• After the initial creation of a snapshot, it can take 4 to 6 minutes to mount the snapshot.
Block snapshots are not created when a volume group is mapped to more than one logical volume.
CLI
• The ibrix_pv -a -o mpath command does not recognize a multipath device. The command
works properly when an argument is added to ignore the standard SCSI devices. Execute the
command as follows, specifying the path to your device.
ibrix_pv -a -o accept:/dev/mapper/mpath10,~standard
• The ibrix_lv -d -s <range of Segments> command sometimes displays a “failed
command” message. Although the segments for which the command fails are still listed by the
ibrix_lv -l command, they are successfully removed from the underlying Operating System
