We can also use a script provided by the XIV Host Attachment Kit for AIX, called xiv_devlist.An example of the output is shown in Example 7-26.Example 7-26 Using xiv_devlistroot@dolly:~# xiv_devlistXIV devices===========Device Vol Name XIV Host Size Paths XIV ID Vol ID------------------------------------------------------------------------------hdisk3 dolly_hdisk3 dolly 10.0GB 4/4 MN00023 8940hdisk4 dolly_hdisk4 dolly 10.0GB 4/4 MN00023 8941hdisk5 dolly_hdisk5 dolly 10.0GB 4/4 MN00023 8942Non-XIV devices===============Device Size Paths-----------------------------------hdisk1 N/A 1/1hdisk2 N/A 1/1We can also use the XIV GUI to confirm connectivity by going to the Hosts and Clusters Host Connectivity panel. An example is shown in Figure 7-31, where the connections matchthose seen in Example 7-25 on page 237.Figure 7-31 Host connectivity panelHaving confirmed that the disks have been detected and that the paths are good, we can nowbring the volume group back online. In Example 7-27 we import the VG, confirm that thePVIDs match those seen in Example 7-17 on page 232, and then mount the file system.Example 7-27 Bring the VG back onlineroot@dolly:/# /usr/sbin/importvg -y'ESS_VG1' hdisk3ESS_VG1root@dolly:/# lsvg -l ESS_VG1ESS_VG1:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINTloglv00 jfs2log 1 1 1 closed/syncd N/Afslv00 jfs2 20 20 3 closed/syncd /mnt/redbkroot@dolly:/# lspvhdisk1 0000d3af10b4a189 rootvg activehdisk3 0000d3afbec33645 ESS_VG1 activehdisk4 0000d3afbec337b5 ESS_VG1 activehdisk5 0000d3afbec33922 ESS_VG1 activeroot@dolly:/# mount /mnt/redbkroot@dolly:/mnt/redbk# df -kFilesystem 1024-blocks Free %Used Iused %Iused Mounted on/dev/fslv00 20971520 11352580 46% 17 1% /mnt/redbk238 IBM XIV Storage System: Copy Services and Migration
