number
The following restrictions apply to CLIMs:
• The maximum number of LUNs for each CLIM, (including SAS disks, XP disk arrays, and tapes)
is 512. Each primary, backup, mirror, and mirror backup path is counted.
• The XP LUN range for each port is 0 to 499.
• The maximum number of XP ports for each CLIM is four.
• The maximum number of mirrored XP volumes is 256 with two CLIMs, and 512 with four
CLIMs.

Each LDEV requires two LUNs. 6
No boot support. 7
Contact HP support for host mode requirements on storage system ports. 8
For more information on supported B-series and C-series switches, contact HP support. 9
Each fabric must contain switches of the same series only—switches from multiple series within a
fabric is not supported. 10
Slot 1 of the VIO enclosure contains a 4-port Fibre Channel PIC, which provides FCSA functionality
of the IOAME systems. You can double the number of Fibre Channel ports on a server (from 8 to
16) by adding a 4-port Fibre Channel PIC in slot 7c of each VIO enclosure. This requires the
installation of an expansion board in slot 7b of each VIO enclosure. FCDM or ESS connections
can make use of these expanded Fibre Channel ports.
Note: For NS1000 and NS1200 servers, expanded ports are available only to customers who
have the HP ESS.

The VIO enclosure software is not backward compatible. This product is supported only on H06.08
and later RVUs. 12
The CLIM software is not backward compatible. This product is supported only on J06.04 and
later RVUs.

Direct host attach
• HP recommends host-based mirroring. For example, each LDEV (P) is mirrored to a separate
LDEV (M) on separate XP ports (p, b, m, mb paths are used). A nonmirrored volume is allowed.
For example, each LDEV (P) is not mirrored to a separate LDEV (M) on separate XP ports (only
p and b paths are used).
• For high availability, the primary (P) LDEVs and mirror (M) LDEVs must be configured on
nl
separate array ACP pairs.
• For high availability, the p and b paths must be in separate XP array clusters. The m and mb
paths must be in separate array clusters. The p and m paths must be in separate XP array
clusters.
• The 2 Gb FCSAs (IOAME) are supported with 1 Gb/2 Gb CHIPs for
XP128/1024/10000/12000/20000/24000 and with 4 Gb CHIPs for
XP10000/12000/20000/24000.
• The 2 Gb Fibre Channel PICs (VIO) are supported with 1 Gb/2 Gb CHIPs for
XP128/1024/10000/12000/20000/24000 and with 4 Gb CHIPs for the
XP10000/12000/20000/24000.
• The 4 Gb Fibre Channel HBAs (in CLIMs) are supported with 1 Gb/2 Gb CHIPs for
XP128/1024/10000/12000/20000/24000 and with 4 Gb CHIPs for the
XP10000/12000/20000/24000.
