The Microsoft Management
Console hangs
The Microsoft Management Console may hang when multiple Storage
Manager for SANs provisioning operations run in parallel through the
Async feature.
Do not perform more than four provisioning
operations simultaneously.
LUN is not accessible
After you successfully create a LUN using Storage Manager for SANs, the
LUN is not accessible from the Disk Management wizard.
After you successfully create a LUN using
Storage Manager for SANs, the LUN may take
a few minutes to initialize. Before accessing
the LUN, ensure that 100% LUN initialization
has occurred.
Inaccurate LUN capacity is
displayed
During multiple Async LUN creation using Storage Manager for SANs, the
available capacity is not reported accurately.
Until the complete initialization of a LUN occurs,
the VDS provider reports the previous
available/advertised capacity before the
provisioning operation was performed.
In a Gateway solution,
increasing LUN capacity may fail
The maximum LUN size grows after extending to the previously advertised
maximum LUN size. In some instances, attempt to extend to the new
advertised capacity may fail.
This is a limitation, when you are using
Dell|EMC storage arrays.
LUN extension fails
Extension of LUN fails if different disk types (FC, SAS, SATAx) are included
in the same disk group.
Combination of different types of disks is not
supported.
NT Backup fails
NT Backup may fail using AX4-5 with EMC VSS hardware provider installed
NT backup is not supported with EMC AX4-5
arrays when VSS hardware provider is
installed. To work around the issue, uninstall
the VSS hardware provider.
Symantec Backup Exec passes
with exceptions
Symantec Backup Exec may fail on AX4-5 storage arrays when the EMC
VSS hardware provider is installed.
Symantec backup is not supported with EMC
AX4-5 storage arrays when VSS hardware
provider is installed. To work around the issue,
uninstall VSS hardware provider.
In an Integrated Solution, LUN
extension fails
LUN extension fails.
To resolve this issue, ensure that the LUN you
are extending is initialized. To verify that the
LUN is initialized, go to Start® Programs®
Dell
Modular Disk Storage Manager. If the
LUN is being initialized, wait for the
initialization to complete.
Extending a LUN size to a value
greater than 2 TB fails
An attempt to extend an existing LUN size value to greater than 2 TB fails. To workaround this issue:
1.
Back up or move all data on the basic
master boot record (MBR) disk that you
want to convert into a GUID partition
table (GPT) disk. If the disk does not
have partitions or volumes, skip to
a.
Stop sharing the volume using
the Share and Storage Provision
wizard.
b.
Launch Clu-admin (take off-line
and delete).
c.
Unassign the volume from the
cluster group and assign to a local
server using SMFS.
2.
Using the Disk Management window,
re-scan the disks to update the extend
status.
3.
At the command prompt, type diskpart
4.
If the disk does not contain any
partitions or volumes, skip to
.
5.
At the DISKPART prompt, type:
a.
list volume
and record the
number of the volume that you
want to delete.
b.
select volume
c.
delete volume
d.
list disk
and record the disk
number of the disk that you want
to convert to a GPT disk.
e.
select diskn
f.
convert gpt
6.
After converting to GPT disk format,
provide a drive letter to this volume.
Using Diskpart, select the new volume
and extend. Using the Disk
Management window, verify that the
size of the new volume is correct. Add
this volume as a resource in the cluster
group. Refresh the Share and Storage
Management interface.
LUN does not failover
The Assign function in Storage manager for SANs only exposes the
LUN/volumes to the hosts and does not assign it to the cluster group or
HA instances.
To include the LUN/volume in the cluster group,
perform the following steps:
1.
Assign the LUN to the cluster.
2.
In the Dell PowerVault Modular Disk
Storage Manager, verify that the LUN
has been assigned to the Host Group.
3.
In Disk Management, verify that the
disk is basic and assign it a drive letter.
4.
Launch Cluster Administration by
clicking Start®
Administrative®
Tools®
Cluster Administrator®
Groups. Right-
click Cluster Group and select New
Resource.
