Specifications
host should not use the volume for data storage or any other purpose. Setting up
this LUN 0 will minimize difficulties during future LIC migrations.
Confirming switch connectivity
To confirm switch connectivity
1. Telnet and login to the switch as an administrator.
2. Confirm that each host bus adapter has performed a fabric login to the switch.
3. Confirm that each ESS host adapter has performed a fabric login to the switch.
Figure 19 shows an example of what displays when you type the switchshow
command.
Confirming storage connectivity
The following procedures describe how to confirm storage connectivity
1. Restart the host (non-clustered configurations) or each cluster member
(clustered configurations)
2. Bring each host system to a halt condition at the console level.
3. Type set mode diag at the Compaq AlphaServer console (if required by the
host) to place the console in diagnostic mode.
4. Type wwidmgr-show adapter to confirm storage attachment.
Note: ESS with the supported LIC emulates the Compaq ESA12000 for
fibre-channel and RAID array 8000 for fibre-channel. Both of these systems
use the HSG80 Controller. For information about how ESS volumes are
presented to the AlphaServer host as HSG80 LUNs, see the following Web
site:
www.compaq.com/storageworks
Differences in storage architecture between the ESS and HSG80 require
different procedures for storage administration. See the procedures in
“Displaying the ESS volume” on page 32.
