DescriptionDefect ID
While activating a Version 2.2 volume group, the original logical volume of the distributed
space-efficient snapshot becomes unavailable if the physical volume associated with this
space-efficient snapshot is in a unavailable state.
QXCR1001077418
A crash dump is not generated if the system crashes when it is booted in maintenance mode
(MMB), using hpux -lm, on a boot disk belonging to a Version 2.2 volume group. When
this occurs, the system console shows the following error during MMB boot:
ERROR: dump device 128:0x2 cannot be used and will be ignored: device
could not be opened.
QXCR1001077961
When more than one vgdisplay command are run in parallel, each instance takes more
time to complete. Also, the system performance suffers noticeably since CPUs are occupied
until each instance completes the execution.
QXCR1001078391
pvcreate core dumps in the HP–UX 11iv3 September 2010 update (1009.01) with the
following stack:
#0 0x4030970:0 in memset+0x330 ()

QXCR1001080721
The pvcreate –B command fails with the following message if there are more than two
paths to the physical volume and the first two paths are not active. The active paths for a
physical volume can be found using the scsimgr command.
No active boot path found! Please ensure /dev/rdisk/disk33 has active
paths and the associated contoller is boot capable.

Known problem and fix for Asian command output
On LVM version B.11.31.1103, when the LANG environment variable is set to any of the nine
Asian locales below, output from LVM commands include extraneous “carriage return” (^M)
characters at the end of message strings. These extraneous characters are not shown on output
directed to the console. However, if the LVM command output is redirected to a file, these control
characters are visible when the file is opened with a text editor, such as vi or emacs. Also, in the
command line interface, command output in table formats might not be aligned and table labels
might not display for some commands, because of these extraneous ^M characters.
This problem is limited to these nine Asian locales: ja_JP.SJIS, ja_JP.eucJP, ja_JP.utf8,
ko_KR.eucKR, ko_KR.utf8, zh_CN.hp15CN, zh_CN.gb18030, zh_HK.hkbig5, and
zh_TW.big5.
The fix for this problem is available with LVM revision “B.11.31.1103.01” (March 2011 Web
Release) which can be downloaded from the LVM software download page: http://www.hp.com/
