Caveats Send documentation comments to [email protected] • CSCsu48426 Symptom: For a data stream that has a lot of variance in the compression ratio across individual tape blocks on the tape, SME restore performance for the HP LTO drives is substantially affected. However, backup performance is not affected. Workaround: This issue is resolved. • CSCsu68490 Symptom: A downgrade from NX-OS 4.1(1b) to SAN-OS 3.1(1) is not supported If there are FC-Redirect configurations and any of the following conditions are true: - FC-Redirect configuration exists for a locally connected target and if there are ISLs configured on a Generation 2module. - FC-Redirect Configuration exists for a locally connected host and if the host is connected to a Generation 2module. Downgrading in such cases might lead to traffic disruption and/or data corruption. Workaround: This issue is resolved. • CSCsu90955 Symptom: In a dual FCIP link configuration with one of the ports is shutdown, the performance of the other still enabled active FCIP link degrades significantly (from ~12 Mb/sec to 1Mb/sec). Workaround: This issue is resolved. • CSCsm32705 Symptom: Disabling Fabric Manager e-mails for Call Home on a port flap event through the server properties is not allowed. Workaround: This issue is resolved. • CSCso31469 Symptom: RMON can not be used to monitor objects for a group of ports of the same type. Workaround: This issue is resolved. • CSCsr42622 Symptom: The TSM catalog backup fails due to a limitation in SME where all tape blocks are expected to be 16-byte aligned. This issue has also been observed as part of the TSM Export Node process due to the same reason. Workaround: None Open Caveats • CSCsc17059 Symptom: In rare circumstances, after upgrading the SAN-OS, a Generation 1 module may be rebooted as it stops responding to the keep alive messages from the Supervisor module. Workaround: None. • CSCsg49151 Symptom: If you bring up more than one link at a time between two VSANs that have overlapping domains and at least one of the switches is SDV enabled, one link will become isolated. The other links will come up, even though the domains are overlapping. In addition, the SDV virtual domains will change, causing traffic disruption on all devices associated with their old value.

Caveats
•
CSCsu48426
Symptom
: For a data stream that has a lot of variance in the compression ratio across individual tape
blocks on the tape, SME restore performance for the HP LTO drives is substantially affected.
However, backup performance is not affected.
Workaround
: This issue is resolved.
•
CSCsu68490
Symptom
: A downgrade from NX-OS 4.1(1b) to SAN-OS 3.1(1) is not supported If there are
FC-Redirect configurations and any of the following conditions are true:
–
FC-Redirect configuration exists for a locally connected target and if there are ISLs configured
on a Generation 2module.
–
FC-Redirect Configuration exists for a locally connected host and if the host is connected to a
Generation 2module.
Downgrading in such cases might lead to traffic disruption and/or data corruption.
Workaround
: This issue is resolved.
•
CSCsu90955
Symptom
: In a dual FCIP link configuration with one of the ports is shutdown, the performance of
the other still enabled active FCIP link degrades significantly (from ~12 Mb/sec to 1Mb/sec).
Workaround
: This issue is resolved.
•
CSCsm32705
Symptom
: Disabling Fabric Manager e-mails for Call Home on a port flap event through the server
properties is not allowed.
Workaround
: This issue is resolved.
•
CSCso31469
Symptom
: RMON can not be used to monitor objects for a group of ports of the same type.
Workaround
: This issue is resolved.
•
CSCsr42622
Symptom
: The TSM catalog backup fails due to a limitation in SME where all tape blocks are
expected to be 16-byte aligned. This issue has also been observed as part of the TSM Export Node
process due to the same reason.
Workaround
: None
