Avoiding problem situations The following sections describe problems that may arise and their solutions. Known problems You can find information about problems specific to the EVA and Command View EVA in their respective release notes. Using the proper service pack with the SSSU Ensure that the required service pack is installed if you are using sssunlm.nlm with Novell NetWare. Otherwise, a critical failure occurs on the second run. See Table 1 for a list of Novell NetWare service packs. Using snapshot or snapclone When you create a snapshot or a snapclone with Novell NetWare, you must present the snapshot or snapclone to a host other than the host from which it was created. You cannot access a snapshot or snapclone from the same host from which it was created. For example, suppose you have a unit presented on NetWare Host A and you make a snapshot or snapclone of it. If you present this new unit to the same host (Host A), NetWare perceives a conflict. Because the new unit is identical to an existing unit, the host assumes that the two units are a broken software mirrorset. NetWare deactivates both devices and informs you that there is a possible broken mirrorset. To access the new unit, present it to a different host from which the snapshot or snapclone was created. You may also choose to present the snapshot or snapclone to a host at a later time, or not at all. 6

Avoiding problem situations
The following sections describe problems that may arise and their solutions.
Known problems
You can find information about problems specific to the EVA and Command View EVA in their respective
release notes.
Using the proper service pack with the SSSU
Ensure that the required service pack is installed if you are using
sssunlm.nlm
with Novell NetWare.
Otherwise, a critical failure occurs on the second run. See
Table 1
for a list of Novell NetWare service
packs.
Using snapshot or snapclone
When you create a snapshot or a snapclone with Novell NetWare, you must present the snapshot or
snapclone to a host other than the host from which it was created. You cannot access a snapshot or
snapclone from the same host from which it was created.
For example, suppose you have a unit presented on NetWare Host A and you make a snapshot or
snapclone of it. If you present this new unit to the same host (Host A), NetWare perceives a conflict.
Because the new unit is identical to an existing unit, the host assumes that the two units are a broken
software mirrorset. NetWare deactivates both devices and informs you that there is a possible broken
mirrorset. To access the new unit, present it to a different host from which the snapshot or snapclone
was created.
You may also choose to present the snapshot or snapclone to a host at a later time, or not at all.
