HP 3PAR InForm OS 3.1.1 MU1 Release Notes

DescriptionItemBug ID
received that spanned two logical disks with different owners. The I/O was
split and passed to the logical disk owner nodes; however, if one of these
nodes failed , the backup node took over and completed the I/O. This was
where the remote copy miscompare was happening, although the backup
node reliably completed the I/O to the base volume on the primary, it did
not issue the remote copy request. This has been fixed.
The handling of the Logical Unit Reset task management function has been
corrected to ensure that SCSI-2 reservations on the addressed LUN are
released.

prevents any characters from returning to the serial port and additional

problems such as filling /var/tmp_log and consuming all system memory.
A fix has been implemented that prevents the deadlock that caused the
issue.
When a controller node unexpectedly goes offline, an alert with Message

auto-resolved when the node rejoins the cluster, but it can safely be deleted.
This alert will not be generated in a future release.
Limitations of the InForm OS
Fibre Channel/SCSI Interface
The InForm OS does not provide user-level control on write caching via the SCSI mode select
command. Write-caching is on by default. Deferred errors will never be reported after status is
sent for a write command. The InServ Storage Server system software may go into writethrough
mode while handling certain events such as loss of battery charge or a faulty node.
The following SCSI commands are supported but are effectively null operations: rezero_unit,
format_unit, seek, verify, sync_cache, send_diag. The SCSI command write verify
performs a write operation but not a verify operation.
Head-of-queue and ordered-queue are not supported. Simple-queue currently defaults to unrestricted
reordering.
LDAP authentication
LDAP authentication using SSL with MD5-signed certificates is no longer supported. This limitation
applies to users of the InForm OS configured to use LDAP for authentication and authorization and
also configured to use SSL and require a certificate.
After upgrading to InForm OS 3.1.1, users who are authenticated with LDAP and who were
previously able to successfully log in to InServ are denied access. Attempted access using the CLI
displays Invalid user or password and attempted access using SSH displays repeated
prompts for the password. Running the checkpassword command for an LDAP user results in
the display of the following error message:
+ authentication denied: Can’t contact LDAP serveruser user is not
authenticated or not authorized
The issue can also be confirmed by using the setauthparam command to set the parameter
ldap-reqcert to 0 and verifying that authentication succeeds.
